Hemi swap wiring, can we use factory Hemi components in a swap, in this video we find out! We take a look at the wiring and what is involved in getting the computer (PCM - Powertrain Control Module) to power up and talk to our tuning software.
Note: This is using the Ram truck wiring.

Fantastic video! Are there any other ways to remove the SKIM then what you’ve shown? Can it be done with a scan tool say?

@MongrelsGarage 2 жыл бұрын

Thank you, as far as I know the only way to remove the SKIM is thru HP tuners…apparently it can be hit or miss with HP on the dodge stuff. Sending it out to someone to remove it tends to be the most reliable options, but if you have HP tuners doesn’t hurt to try it before sounding it out.

I have an update to your question, HP tuners can be use to turn off the SKIM. Please check out kzfaq.info. These guys are great and very helpful!

@MongrelsGarage 2 жыл бұрын

Update to this comment: You can definitely reset/disable the SKIM (NGC PCM’s) using HP Tuners but you need to know the proper sequence of events, it’s not as easy as just turning it off in the system settings.

A couple things I would add - Most multimeters have a continuity ("tone") function that emits an audible tone when continuity is present. This is often a better way to check wiring continuity than just the Ohm function. Another tip for this is to use an unfolded paperclip with an alligator clip test lead for testing connectors with tiny pins like the 0.64mm pins used in some modern automotive applications. Another helpful item you could add to your bench is a lab power supply which will give you a reliable, configurable voltage and amperage power feed for stuff like this. It will also help you with testing 5V based automotive components or checking components at an alternator-like system voltage and is smaller and easier to deal with than an actual battery.

Quick comment in regards to the later 58 tooth reluctor. I've been told that Hotwire Auto's kit uses an '09-10 NGC controller for the later motors and only requires swapping some sensors. Doesn't mean that the controller doesn't have programming changes, but it would imply that the '09-10 NGC controller can be read the later 58 tooth reluctor.

@MongrelsGarage 11 ай бұрын

I do recall doing some research on this and yes, if you change the crank sensor the new PCM will read the old reluctor (100 percent confirmed this) and vice versa the old PCM will read the new reluctor.

Well I can for sure say a 05 & a 07 will not swap over. Even if you change the key, skim and pcm. I just changed all 3 and the lights would come on. And there wasn’t any security light it went off. But as soon as I went to crank it, it did nothing what so ever. Like a dead battery. TY for at least messaging me back.

@MongrelsGarage Жыл бұрын

I would imagine you will need to do some tuning. However the 2003-2004 Rams with a Hemi used a throttle cable and were not drive by wire, if you could find those components in a junkyard it should bolt right up. If you are using the engine from a 2003-2008 as your donor then you could use the 2004 PCM potentially, you may still need to match up the VIN which will take a programmer to do. Hope that helps you out.

Just discovered your channel ! I have Much too watch!!! Can i ask some specific questions , which HP tuners would you suggest to access my 07 Grand Cherokee 5.7 ? will i need to rewire the OBD2 port as you have here to connect to the HP tuner ? and am i correct to assume if i rewire as you have shown in this vid the engine and PCM could then be retrofitted into an older car , and operate not requiring the skim systems? Many thanks .

@MongrelsGarage Жыл бұрын

Thank you for the sub. There really is only one HP tuners…they have different interface tools, but the software is the same. If you want to do live data logging and a couple more advanced features then you go with the pro, but the standard package will work for this. I use the MVP2, but I believe they are now selling MVPI3 which is just the new version of the interface tool and will work fine. There is no rewire required if you are using it on an existing obd2 equipped vehicle. This video is for taking a junkyard system (from a Ram Truck) and using it in a older car (swap). You will need to wire an obd2 port into the older car. The SKIM is just the security for the PCM, you will need to reset it. I don’t go into it in this video but DIYHEMI (sublime technologies) has a specific video that shows you how to deal with SKIM.

Unfortunately I don’t play with the cars much. However the 2010 may plug and play sort of. You will certainly need to program it with the VIN from your car and reset the SKIM. The 2010 PCM is still very similar to the 2008 so you may get lucky. I would reach out to DIYHEMI (Sublime Technology) to see what they have to say.

Great information, so glad i found your channel. I have a complete 2004 Durango chassis that i plan on putting under my 73 IH Travelall body. I was thinking of just using a GM style universal wiring harness from painless to run the interior. Looks like the only connector i really need to touch is the white connector other than the OBDII hook up. My questions are: How to wire the acc/start from a keyed ignition in the dash? Would i just take the yellow wire from the painless ignition to the yellow wire on the dodge harness? Second, where would i tie in the fuel pump wire? to the PCM or straight to the fuel pump itself? Lastly, where is the best place to get my dash sensors information and would that even work with older analog gauges?

@MongrelsGarage Жыл бұрын

Assuming the yellow wire from the painless harness is the start signal, then yes you would wire that to the C1 pin 30 yellow wire. I do have another video specifically for the start circuit. As for the fuel pump…it depends, if you want the PCM to control the pump then you wire in a relay and let the PCM control the ground side of the relay. As for the dash sensors there are a few options. You can install separate sensors compatible with your dash, or you can spend some time converting the incoming signals to work with your instruments, or you could even run some gauges off the OBD 2 port.

@@MongrelsGarage great thanks so much for the reply. I don’t have any tuning capabilities. Are you willing to tune my PCM for a fee or is there somewhere I can send it?

@MongrelsGarage 11 ай бұрын

Sorry, I don’t do tuning, the good news is, depending on the PCM and application you may get away with not tuning in the short run. If you have a black key from the donor then it may not have SKIM and will fire up for you. It will throw a code for rear 02 and maybe some Evap codes but should not effect it’s running. There are a couple places that can tune though, except you might be better off getting a 2005-2008 PCM if you can as the 03 and 04 are limited as to how much tuning can be done. There is also HP Tuners that you can use yourself.

Hello, you have to take the back cover off, then on the front side there is a red lock the needs to be pushed/pried. When looking at the front of the connector the red lock will need to go to the left. Then you need to insert a pin extractor into the front of the connector in the smaller slot to unlock the wire and gentle pull it out from the back.

@MongrelsGarage 11 ай бұрын

Honestly my tuning skills are in their infancy, but I would say no and additionally you would not want to, as it protects the driveline from much greater damage. What you can do possibly is address what is causing the limp mode. If there is a sensor that is no longer used after a swap you can tell the system to ignore the sensor input, for example EGR or Evap, however those type of systems rarely cause a "Limp Mode".

@MongrelsGarage Жыл бұрын

You will need to decide what functions you want to keep. You can leave the donor harness intact or thin it down to only the items you require. For the most part you will need to supply power and grounds to the PCM, and at least three relays. The Auto shut down (ASD) relay, Fuel Pump Relay, and starter relay (on your 06 this one can be controlled thru the PCM or be standalone). You will need certain sensors hooked up and as you mentioned the gas pedal. You will also need to be able to tune the PCM, I recommend HP Tuners, however other options are available.
