Rewiring a car...

[Drmoussaka]

Here's a Noobie question...

So i pulled my wiring harness out of my car for a complete restore. Looking through the wiring harness i come to think of some options that the car came with that i nessasary dont want back into the car. I there an easy way to rewire this so the car runs well.

Are there any kits out there to help with this? Has anyone done this?

Why would you want to put yourself through the pain and headache of removing a few wires?

Because its a project. Just looking for a couple little ways to make it easier if possible.

Like what? Some things as you can probably tell Unplug from the junction on the driverside near the firewall.

hes gonna make the DC Cole LTW wire harness

Yeah but like the wires for the heated seats, whats it take to remove that, or the wires for my electric top that will no longer be needed, wires for the anything else that i might not need.

I dont know what that is.. could you elaborate?

DC Colegrove claimed to have removed something ridiculous like 500lb from his car with a lightweight wiring harness. Probably saved more like 5lb removing the odd wire here and there.

but i bet if you made all the wires single strand wires...

Hahah well im not about doing all that (or claiming such false statements) Just looking for a way to remove wires that i wont need and not have an issue later down the line with check lights on or things not working right because they are connected to each other somehow or another. I dont know much about wiring so im going to have to take very close look at things.

When i as removeing the harness to begin with i came acorss like 5 different sets of alarm, headunit, sound system wires that were just tucked away and no one removed them all when installing a new set. Was quite iritated. I would say about .5-1lb already has been removed by just that itself.

But im not doing this for the weight savings. so it wasnt a concern that way.

For a street car, leave the stock wiring harness. If you remove any feature (like heated seats, cruise control...), just follow the wires as far as you can and remove them.

If you're building a dedicated track car, it may be worth building a new wiring harness. I am planning on doing this with my M3. In my car, there is almost nothing left in there that requires me to wire up, so it's worth it to start from scratch.
Really, all I need to wire up are fuel pumps, ignition, electric fan, gauges, ECU. I'm running on all circuit breakers too, so no need for fuses.

James Crivellone (I.E. - Site admin) removed all the "excess" wiring from his car. Figure out what wires you don't need and pull them out of the harness. It's that simple. Then just tape everything back up afterwards. I did this with a kit car we have that used a donor car's harness. I literally removed over half the wiring cutting out the stuff the kit car didn't need/have.

Looks like good info. Need to take a deeper dive into it to see if this is what i need. But thats alot for the info.

Sounds like a great project. For someone thats not electronically inclined. I need to read read read and more read on this.
