Luis Zepeda what happened to your face🤔

well, all my vehicles have factory tachs.. so you have to wire one in like that if you dont have one in the dash.. i dont know if you are saying i did a shit job but thats the only way to add one..

RIGHT DUDE GUY IS AMAZING

it will drain your battery

Find a “switched” circuit to plug the red wire into or you’ll drain the battery. Green goes to the negative side of the coil, or the connector on the distributor cap that says “tach”. Watch the video. It shows nearly all the possibilities for the green wire.

Sounds like it doesn't have a wire for your light

what kind of vehicle.. ? the starter doesn’t have anything to do with HEI.. or did the car used to be points ignition?

Chris Craft 1972 El camino. It has hei dstrb on it but the stock starter had a wire to "s" & a wire to "r" new high torque starters don't have a place for both wires

HEI does not use I or R,,,, that is for points ignition...run 10 gauge purple wire to S only

Check your grounds. Then check all the spark plug and coil wires. And cap and rotor.

@@TheAwmartin Thanks, the Tach went bad. Have already replaced it.

there has to be a way to switch the tach to v8.. i doubt gm made 2 tachs that look the same but are different

That's it the 3 or 4 tachs I've bought ALL have a switch on them, marked 4, 6, 8, so, there you go!!! Find the switch!!!

you just have to spice into the wire going into it.. make sure you fuse it so you dont mess anything up.. just a little 10 amp fuse will due

Buy what is called a Add-A-Circuit fuse holder or also called Expandable Circuit on Amazon. Or simply look for fuses, they will all come out. This is like a fuse adapter with 2 extra circuit extensions for connecting 2 more fuse circuits. It also has a red wire on the side. Keep in mind that the "ign fuse" is only a temporary power circuit, by this I mean that as long as you put your key on the ignition and switch it to On or turn on the engine, that's when it will turn on whatever you want to turn on at that time. For example a radio. The radio will only turn on as long as you have the key on On or when you actually turn on the engine. If you want your radio to turn on whenever you want with out the keys being on the ignition switch, you have to find a permanently powered circuit (as long as the car battery in connected of course). To do that you have to poke wires with a test light to see which wire is hot (powered on) all the time with out the key in the ignition. If you want temporary power circuits, poke a wire that doesn't and then switch the ignition to the On position to see if the light on your test light turns on. Switch the key to the off position and see if the light on your test light turns off. If those 2 things happen, you got a temporary power circuit. There's also another option for connecting extra things to your car. You can also connect it to the wires that power up your radio, your cigarette lighter, the dash lights, or even directly to the battery positive post with a very long wire. But why bother using a very long wire that goes from the inside of your car going all the way to the car battery when you can find power any where under your dash. Also don't forget, whatever you are connecting, it has to be grounded. Always connect the black wire to any metal part on the car with a screw. Try to install the wire to screws or small bolts that are factory installed. You may have to lightly sand the metal to remove paint or rust to make sure you get a good ground. Hope this helps.

heather braun 🤗

hook it up the same the extra red and black are probably for the light

Chris Craft thanks ill give it a try

Kool bro 👌👌👌

that car has a tach from the factory..

@@chriscraft77022, yes Sir, it has but the whole cluster is not working, and I cannot find a replacement one. I am trying to build a custom cluster with analog gauges and digital addition using raspberry pi.

@@mohamadnbadr find the tach signal wire to the cluster... use it ....or find where it connects on the engine

@@chriscraft77022 thank you, very helpful.

doesn’t that car have a factory tach?

@@chriscraft77022 My does not have a tach only gas,temp and speedo it's a manual trans

we’ll find out where the factory tach wire goes or is connected to ...

@@chriscraft77022 I found it after so much searching maybe if I do a KZfaq video it will help several others

@@chriscraft77022 thank you very much and for the fast replies aswell amazing

negative side of coil.. on distributor cap it has a place labeled TACH on the left

Got it Thanks

I have an automotive grounds explained video you should watch

no

😂

if it has a single coil just wire off negative side.. the green tach wire

I have never fused a tach but if you wire off a spade from the fuse box fuse the red wire to the tach

I'm more worried about the illumination, I'm wiring in 4 total and don't want to overload the fuse or, if it's not fused I'll be adding one, it's for a 64 Malibu with a 396bb and it's not mine lol.
