Which wire harness company?

[347strokin]

Hey guys,

I'm slowly moving along with my LS3 swapped 87'. I was going to tackle the wiring myself but I don't feel 100% confident in my abilities and I'd rather just have it done right and plug and play.

With so many companies out there building harnesses, can someone recommend a company they've had good experience with? (1987 C10 to an LS3 with a 4L80E trans).

Thanks! Didn't realize we had a fellow member building these.

You're welcome. I'm not sure if he does what you want specifically, but I wanted you to give one of our guys a shoutout before you looked somewhere else. Good luck!

I used Performance Systems Integration when I did my 69 C10 LS swap with 4l60e. The harness was very well made and put together. It was very simple to install and they had everything available to do the swap on their website (brake pedal switch, computer bracket, etc)

Thanks buddy, this is exactly the route I'm going. Going with the full kit as I need the pedal, TCU, 02 sensors etc. Everything is completely plug and play to both engine/trans. Pricey but the convenience and quality is worth it.

No problem, glad I could help. Good luck with your ls swap!
