This is a highly underrated tip.

Ya good idea, but I doubt the cartel members using this could read them.

I leave a mental note : "That's future guy's problem." Almost always, future guy is me.

I did something similar to this for my car. I put a sticky note on the wiring diagram page of my Haynes book, and drew the wiring changes on the sticky note, lined up with the diagram on the page. It also doubles as a bookmark.

Best comment!

Trudat!

The Grand wizard!!

talk is cheap, car wizard is not.

Multiply that by 8 billion people on earth

Correct & I might add the word desire. Thank God we have a few good people left that put pride before the almighty dollar bill. That's becoming less & less nowadays. So my hat's off to you Mr. Wizard!! I wish you were closer to me so we could do business. Have a beautiful day!! Illinois, USA

I went to two different places they could not figure out my engine was bad in my Silverado . I traded it on a Honda

I would have, it’s pretty standard to run the car on the lift.

I've got my own Car Wizard here in Detroit. Mechanics like this are a rare breed. Shout out to Alex at H&A Complete.

@larrywade9041 Thank God he is close to me. When i need work done, im only going to the Wizard.

Mr &Mrs Wizard , The instruction and confidence that is brought forth via your words and video's are most incredible. Always have enjoyed them cause they are real world real time. Continued blessings and more Lake time your way. Sincerely Marc F Saiber

That was one of my problems with working at a dealership, they rarely let you do things like that. It was either, order parts straight from the mfgr or GTFO.

I wish you were in Colorado

I love how honest you are it will bring you a long way mr wizard

Does bypassing the rear module set off diagnostic code, saying rear blinker light faulty?

@@shan6021 I don't think so but I might be wrong

así que,,,,, no enbArre

true so true👍

yeah he digs as deep as he has to in order to find out what's going on what's really going on with a vehicle and causing problems

That’s exactly why you are correct

I second this. I am retired from a car manufacturer after decades there and pior years at a dealer too. I do lots of repairs by soldering broken internal connections and have overlayed transistors for failed ICE chip power stage but I restrict it much more as I was burned by someone for doing those kind of repairs when an unrelated failure occurred 2 years later. The lighting on many domestics is done just like this G-Wagen now and many will not keep failure indicator or codes cleared when a bypass is done. The source module may include a circuit integrity check when the light is not operated and can detect the tagged on load of the bypass lamp. They don't have workaround repair tolerance as an engineering criteria.

Shops outside the us don’t do this repairs any more, too. Lawsuits aren’t a problem here, but it’s easier to replace something then to come up with a solution. Additionally, you don’t need educated personell like th3 wizard, replacing a wheel bearing is something a mediocre mechanic can do… sadly it’s just replacing today, no longer repairing…

@@erebostd I stopped working at new car dealerships way back in the mid-70s, and even then they were getting more and more into parts replacement. At each dealership I was the only mechanic who tried to diagnose instead of just throw parts at a car. The dealers always had a "warranty room" where they kept bad parts off of newer cars, so they could pay my diagnosis and repair labor through phony warranty claims using those parts. That was the ONLY way I was going to get paid. Went into business for myself after the 70s.

@@erebostd It's generally a cost issue to not repair but replace things, combine that with any possible warranty issues it's safer to just replace and then you can blame the manufacturer for a failure. Some shops can do that repair, but they tend to be older guys with mechanical engineering experience. Many just aren't equipped but might pass jobs on to an engineering specialist. Again this falls to the overall cost of repair vs replace. Do a repair which fails and most people think you don't know what you are doing. Very few people have the experience to appreciate the difficulties of repairing things in the first place. Even second hand parts shopping can be time intensive. I was watching Vecor, and he bought a toyota that was written off - not because of the damage to the car, but because parts were scarce and the expected time frame to repair the vehicle exceeded the cost of the insurers rental outlay to their customer. Many years ago I went to a radiator shop to see about having a motorcycle radiator which was damaged in an accident repaired. Very lightweight aluminium and the shop owner looked at it and explained the difficulty of the job and ultimately rejected it - from his perspective there was a high chance of failure which meant overall it could be more problems than it was worth. Radiator was worth $500 or more at the time IIRC. As I was leaving one of his employees grabbed my attention and looked at it. For $50 he would have a go, no guarantees. Worked out well and radiator lasted for years until I sold the bike, but I don't fault the owner of the business for turning it down.

My first thought as well. Ebay LEDs not putting enough resistance on the system.

I thought of that too. Newer cars usually works like that. You need to wire a resistor in to make it work.

Would be funny if Car Wizard replaced rear Sam just to find out it did not fixed the issue because of the resistance.

@@EvzenEmanuel I mean, he left the rear SAM unit as it was, so his repair is completely reversible.

I bet that's it's gonna burn out the front module now. I would just add an optical relay for 20 bucks so it doesn't affect the circuit.

@@philipparana9225 That claims make absolutely no sense at all. The lights are all 12V, adding a LED turn signal into an existing circuit that is putting out 12V will obviously not harm anything, especially since the load from the LED is very low. It is elementary electronics engineering...

Kind of curious about that. Your theory makes since, especially being aftermarket tail lights. I was thinking insurance fraud / brake checks would make more sense than kill switch for brake lights, but your idea makes more sense. Seems like a "set it during install and forget" kind of thing. It would be silly to put the switch there for insurance fraud as you can't pop your tail lights off and flip the switch with other people watching before the cops get there. Very unlikely anyway. On that note a crim isn't just going to want to turn off brake lights. They are going to want to turn off brake, tail, turn, parking, license plate, maybe even dome to prevent accidental turn on. Pretty much everything but headlights and maybe dash lights. If they just wanted brakes I would think it would make more sense to go after the switch on the brake pedal. Then the switch would be accessible for the driver too. That said is seems like jumpers or something that can be heatshrunk would be a better option for the manufacture of the tail lights, if that is what it is. A switch like that getting exposed to moisture will lead to failure.

@redbaron6805 just because they share the same voltage does not mean they have the same draw. Hence , the led lights have hyper flash when put on a relay for incandescent. Voltage is simply pressure, rapid cycling relays (turn indicators), especially mechanical ones like in this 20 year old design are really sensitive to prolonged over or undercurrent. In this case, he is tapping the output of the front, which is gonna rob power for the front light to run the led. He may get away with it since led uses so little current. A optical switch would only be looking for the current to use as a signal to open and close its own power supply for the light. I'd use optical because it won't fail in a blinker cycle time and are really not expensive at all and would keep the non oem light 100 percent isolated from the car provided it was fused.

@@philipparana9225 I understand that point, I'm an EE myself. The reason you get Hyper flash is because the blinking mechanism in most cars uses a Bi-metallic strip, which makes contact, heats up and expands, and then releases when it is hot, cools down, and then repeats the process. It is not a traditional relay in the traditional sense where a contact is activated with a separate voltage input. This process relies on current flow. And the current flow is designed around the total current draw of the flasher bulbs on the front and rear of the car. Hence, the hyper flash is actually a feature to let you know one of your turn signal bulbs is out. Hence, when you change either lamp to a LED, or both, the current flow is lowed, and the flasher design means you get the hyperflash as a result. There are usually two solutions to this. Either replace the flasher module with a LED replacement module, or add a load resistor on the turn signal line to simulate a incandescent bulb. So, the only "sensitivity" is the flashing speed is designed for a specific current draw. The LED flasher replacement replaces this current sensing design with a traditional timer relay circuit, which turns on and off using an IC timer, ignoring current draw. In the case of the G-Wagon, since it has two turn signal modules, they are most likely IC timer or CANBUS based, and will flag turn signal failures using a computer signal vs hyper flashing. Many European cars use CANBUS bulbs instead of this load circuit design which is mostly used on American and Japanese cars. CANBUS bulbs have specific resistors where the computer monitors the current flow and flags bulb failures when the current flow is too high or too low for the circuit. So, you could be partially correct in that sense, that the computer system could flag the current draw if they use a CANBUS system, OR the lamps would hyper flash, if they are using the Bimetallic strip system, but not both. You could use a relay circuit in this case if this modification was causing an issue. But, in this case, it is obviously not causing an issue. There is neither hyper flashing going on, nor is there an error being set in the CANBUS system. Hence, as it works fine as it is. There is very little need to do anything except just put an inline fuse for the power line to rear lights, in case they short out in the future, as the rear module fuse is probably being bypassed in this case.

You are blessed! I would like to visit the Omega shop! I have an extensive background in the Machinist trade, auto, aircraft mechanic, carpenter, painter, tile setter, and Sheetrock hanging/ finishing!

Yes agree!

yeah that would be hard to anticipate, well depending on where you live i suppose. how did they manage water getting in there in the first place :D

@@juki6377 air compressor that has never been drained.

@@grad0n seems risky

Yeah, no kidding, the Wizard was going on about how beautiful it was, and I was wondering if he was looking at the same car as me, because the front end of that G55 is as straight as RuPaul's Drag Race. The fact that the owner of a used car dealership bought this as their own personal ride without realizing how absolutely sketchy it is tells me I wouldn't take a car from their lot for free, much less buy one. This G55 might as well have "drug dealer" in LED lights on it, because I'm pretty sure that's who owned this.

@@megachonk9440 I have worked around used car dealers and wholesalers, these guys will not take a nice car that they bought cheap for their personal car, they just look at as they are wasting profit. They rather have as their personal car one they bought cheap and maybe has a salvage title or one that cosmetically looks good put has expensive problems, so they spend as little as they can to make it useable and don’t care about putting miles on it cause usually they are high mileage cars.

Definitely looks like a wrecked car. Is the front axle a replacement from a different model and that is why the wheels wouldn't fit?

yeah that's all I could see lol

​@@carlwest859 It was likely just some surface corrosion that prevented the wheel from sliding on. Worst case the hub center might have been slightly ovaled due to a heavy impact, but is extremely rare. It may also be that those aftermarket rims were not machined to proper tolerances.

Use a heavier gauge wire because a long run has a larger voltage drop. Or, figure out where it comes from in the front!

@@leonardodavinci303 Thanks for the wire tip, I will do that.

Before you run the wire, check if the module is happy running both light bulbs in parallel, cause it might trigger over current and not light at all.

And he will say 'Gee Gramps, you're a real wizard with the cars!' Winning!

@@ikocheratcr Good thought. Maybe I should switch at least one bulb to LED?

The reason why you don't see this today is because if that so called genius repair fails the wizard will be sued into oblivion by the insurance company.Replacing the modified parts with new OEM parts is the correct fix, not what the wizard did.

The person who put the tire on the rim must've been new,because anyone knows to check each tire for damage before install.Even new ones can have shipping,or manufacturer damage.

Your can clearly tell he's passionate about ethics in the industry.

@Jimmy Two Times False. It is ABSOLUTELY a damage multiplier. The only thing those do is turn a $3,000 insurance claim into a $10,000 insurance claim.

​@@willmtaylor It's a damage REDUCER for the Mercedes. Lol

Probably only survived because its built like a truck 😂

those studs can handle the load whether the wheel is off-center or not. The section that was cut out only centers the wheel.

@@adotintheshark4848 Thank you. I keep seeing this myth everywhere. The hub ring does not support the weight of the wheel when torqued down properly. I went years without using hub rings and had no issues.

had wondered how the wheel lug taperes looked cause if it was moving that much i woudl think the holes would be wallowed out at least a bit. sure it costs more but im in the replace the hubs (120K likely need them soon anyhow) if the new hubs and wheels didnt fit turn the shoulder to the rim spec. new rims only if the holes are looking bad

​@@adotintheshark4848 Thats very incorrect information. The hub is supporting the weight of the vehicle and transfering bumps, etc... into the hub. The wheel studs are only designed the pull the rim against the hub. They are not designed for sheer forces. I've seen numerous vehicles bust wheel studs, some even have the wheel fly off while driving, due to using wrong rims or adapters that don't use the hub centers.

Classic crim car mod, shame these buckets get mangled by miscreants like this.

This is the worst car ever to commit crime with. How many silver G wagens are in Kansas? Lol

@@thelastmemphian This one!

No shit Sherlock. Car Wizard says exactly that in the video.

@@thelastmemphian It ended up in Kansas but that does not mean that is where they used it, might of dumped it off there, or the cops got them as they were just driving through Kansas.

Maybe so, but it would look better, feel better and work better until it broke.

That's why Russian engineering made a proper sledgehammer...

Truck?

Yup. Trigger the relay with the signal from the front module and power the relay from the rear module, or really any power source of your choosing. 15 years installing car audio taught me lots of unique ways to utilize relays.

OTOH, if this car came with incandescent bulbs originally, won't these LED's be well under the design load?

@@theundergroundlairofthesqu9261 that is very likely. Often times adding LED bulbs without adding resistors inline can make the vehicle think the bulb is burned out or missing. In most cases the bulbs will still work, but the vehicle will do the "fast flash" of the turn signals, as if a bulb was burned out, However due to the complicated lighting system in this truck it's possible they just wouldn't work at all. However, that doesn't explain why the fronts are working, as I assume the are LED as well.

One has to wonder if the aftermarket LED tail lights on this vehicle ever worked. I would be curious to see if load resistors would have made them work with the rear SAM.

@@DriverDude100My money is on this…. Original lights would fire right up Id bet.

Maybe you might become friends with a machine shop to get the work done. We used to have a machine shop that if they couldn’t fix it, you made a mistake, a big mistake, in buying it.

Exactly.
