Default New wiring harnesses

This is my first post so bare with me. I’m sure it’s been covered already but I couldn’t find it.

last month I bought a 73 and I swear the guy before me probably had a methamphetamine addiction. He halfway installed an Isis power management system. But he didn’t color code anything, only the mechanical needs of the car are met. So windows, head light, heater even etc are not hooked up. The connections are all hear shrunk butt connected.

So I want to completely start over from scratch. Painless seems like a solid choice. Does anyone have any suggestions on a harness that works better than others?

This is what all the wiring throughout the car looks like

I bought harnesses from Lectric Limited. I’d say they are closest to original that you’ll find.

Got a Lectric Limited harness for my 69. Was very nice. Perfect in every way.

Are you wanting to try to salvage any of the Isis system? If not, go with Lectric Limited.

go with a Lectric Limtied or M&H. they are plug and play and use all BRAND new connectors and are 100% like factory so you can use GM wire diagrams.

How about the American Autowire brand of harness products? Specifically their 'Factory Fit' line? I noticed they also offer some C3 specific harnesses...

thanks,

Hi Mike,
I recently installed all new harnesses from Lectric Limited in my '69 and I'm very pleased with them so far. You're welcome to come and check them out if you'd like, just PM me to make arrangements.

Welcome to the Forum,
