Has anyone installed a universal chassis harness? Options

[zach914v8]

My chassis wire harness is garbage. Recently the wires have started to disintegrate and I have shorts everywhere. When I fix one spot somewhere else fails, and I have to band-aid more crap. I am starting to worry about my car catching fire, and I'm tired of it.

My car is a 74 with a carbed v8. I'm not thrilled about the prospect of buying a used 40yo harness either.

My question is have any of you out there installed a painless/universal chassis harness in your cars?

If so how did you wire the dimmer/light switch/pop up headlights and 2 speed wipers?

What problems did you come across, and what fix it?



Thanks

Its pretty simple. Study the factory wiring schematics then compare them to the universal kits. Its apples and oranges, nothing fits and the universal kits are not complete.

Then think about how to connect things - are you using the original factory switches, relay board? You already mentioned using a GM ignition switch. Ugh.

Anything can be forced fit to make it work out of necessity, but there will be sacrifices - in quality, reliability and performance. Once you put in something like that is an obvious kluge job, think for one second about what that does to your resale value and who can maintain it.

Resale is of no concern whatsoever to me, and I do all my own work so got that covered.

Thousands of people, myself included have used a painless wiring kit. I would hardly call that set up a "kluge" job as you called it.

Lot of very beautiful installs with that kit in hot rods all over the world.

I probably wouldn't use a single factory switch if I didn't have to. I like the idea of being able to go to any parts store in america and buy the parts I need for my car.
