Do some searching on here, as there are a ton of aftermarket or custom built standalone harnesses ready to buy.

If you have the skills and can read both pin out and wiring Diagrams.. you can DIY it. many have. But if you have the Cash, no time and don't want to take it on, Then yes.. send it out. .mamy company on that will do it.

I am sure the usual Sponsor will ping in soon..

A new Custom Harness wlll usually look better as it lays out. You can get a Stock OEM one to look good, but it take some time to take it apart and put it back together to layout looking good.

if you are going to take it on yourself.. many on ths forum will be able to answer you quetions.

either way.. good luck

I would go with PSI conversion.It will be worth the cost and it will be all new wiring.You could probably sell your harness to get some money back.It will save you alot of time and aggravation.

I can make you exactly what you need or rewire your harness no problem.

On thing to remember is if you use a factory harness you are stuck to the factory length. Plus its hard to make a factory harness look as good as a new one.

One thing to look for and to think about when you are looking for a harness is what is included if needed

Fan Relays and wiring?
A/C relays and wiring?
Starter Relay and wiring? (Very good to have for clutch or neutral safety switch.)
Fuel Pump relay WITH WIRING.

In the end you should look around and see what is with the harness when you purchase it. There are companys out there who will sell a new harness for $350, but they use repair tooling to manufacture a harness ( big NO NO) or they are bare bones with no relays or sometimes no O2 wiring. Some use their own color codes and not GM color codes.

You get what you pay for. Pay now or pay later. There is no way around it.

What are the engine and transmission from? Are you putting AC in the car, if so what kind (eg vintage air)?
