To start off with I know less than nothing about electrical wiring . The problem I'm having is I'm trying to wire my new build that has no wires at all. I have a Hot Rod wire , 18 circuit universal harness. It's labeled just fine but trying to switch from mopar wires to these wires is killing me. I no longer have wipers , heater , a/c all that kind of thing. I still have lights and turn signals and all of that. . Is there something out there that can tell me what wire is for what in the mopar stock harness. I have a blown up diagram but obviously that isn't helping me much. HELP !!!!!!
 
LOL YEH. There's something "out there." It's called a "factory service manual." But you did not tell us what you are working on. Many years of service manuals and wiring diagrams are available at MyMopar
 
Oh wait, "blown up diagram." Didn't see that From where? Can you post it?

You know how to photograph and crop/ resize? You can post sections of it here
 
I rewired a 60 el camino with a painless harness. Most of those aftermarket harnesses only come with 1 fused hot wire feed for wipers and 1 fused hot wire feed for blower motor. You have to make your own wiring sub harnesses going out from the wiper switch to the wipers, and out from the blower switch to the blower resistor and blower motor.
 
Some of the new wiring harnesses use CANBUS. It' basically a modern system that uses wireless technology, retrofitted to our old Mopars. If you're starting from scratch, it's the way to go. I recently rewired my son's 1983 W250, and it great. Minor programming required. Paul.
 
Old cars are supposed to be simple. Adding micro processors and CanBus tech muddy that simplicity. Personally I dont like computer tech in old cars running anything unless it's a bluetooth setup for music.
 
The light harness for the same series would help a lot and usually those wires are still good since out of the heat zone. But, if adding relays for the lights, as many do, you will be hacking that too. The engine wire is fairly simple if a 1960's car. Junkyard wires are usually useless since friable insulation. If retrofitting HEI that needs to be customized anyway. If using the bulkhead connector, most critical is to get the engine-side plastic holders from a junkyard car (or new harness from Year One or M&H). Some install a custom bulkhead or just straight-wire thru as most/all modern cars do.
 
There's no heater , wipers or any accessories . The main problem is the wiring from the steering column to everything. I have a bunch of manuals . I also have the stock wiring harness , which I think I will use the plug to the column and figure out which one I need and which ones I don't. Thanks for the responses. it's a 70 dart
 
If you can afford it, go with a factory correct reproduction by M&H. It will be very expensive. HOWEVER, since you stated you know less than nothing about wiring, I am afraid you have very little chance to successfully rewire an entire car with a Painless kit. At least with an M&H kit, the wire colors, lengths, and connectors will all be perfect and match a good wiring diagram perfectly. I really don't want to disrespect you or your attempt to tackle such a difficult job. A complete rewire like this would be a painstaking job for someone who was fairly good with wiring. I am pretty good with wiring, and what you are attempting would be something I'd rather not do. I am afraid that a person at your level might have trouble following a diagram and altering it to fit a more universal kit. If you can afford it, you will not regret buying a factory correct harness.

I appreciate your candor . The lights I got , the engine bay I got. The only thing is the plug to the steering column that energizes everything. I still have the factory wiring and I'm bound and determined to get this . I'm thinking with some more reading I may be able to pull this off. It's the mopar routing everywhere that is getting me... from a switch to a relay to a junction block to the starter. 30 wires are in the harness and I only need the 1. Do I need the relays? I'm caught between do I need this or not. Looks like I'm going to have to figure this out one wire at a time. Now if you're feeling generous I have an extra room and I make the best BBQ in ARIZONA
 
It sounds to me like you are a fast learner. A guy who knows less than nothing would not be able to get as far as you have.

I'm trying . If it was a chevy there would be no problem. But I guess when you're the best ( mopar ) you have to be dififcult. I was just thinking someone had some short cut or info on the steering column hook up so I can use the key. Make no mistake , I'll get it.

With an attitude like that, there is no doubt in my mind. If you do hit a bump, there are plenty of people here who can help.
 
One wire at a time is my advice...work out where both ends go each time, finish that one move to the next one...as mentioned there are some colour coded wiring diagrams to be had at My Mopar... thats a good start ...Im in the middle of this too...its quite the task but stick at it

I've made some head way. I'm stuck at the coupling for the steering column. Taking your advice on My Mopar. Do you know weather or not you have to have the bulk heads , ballast resistor or starter relay with an after market kit.
 
Im in the process of deleting my bulkhead completely, ballast resistors went when I fitted the MSD box and dizzy, starter relay is going onto the fuse/relay panel under the dash

When I rewired mine , I had to find the correct wire and match it to the mopar column plug , takes a little doing to change them over correctly -----------
Also cleaned and used the stock mopar wiring (3 speed) for the wiper motor.
