From what I can recall, orange wires are constant 12V, pink are switched 12V and all black are GND. You should be able to find a pinout diagram online where you can find what wires control the fuel pump and cooling fans.

Speartech makes the best plug and play harnesses but its pricey. I priced out everything to have mine done and it was $1150.00 for true plug and play plus I had to ship my stock harness down and have mine shipped back at my expense plus wait a few weeks which at the time was out of the question. I too was going from a factory carb car over to fuelly.

So I ended up doing it myself and it was time consuming and fairly tricky but with patience and some dedication its totally doable. Took me and two helpers about 16 hrs ( over 3 days ) to make a nice job of it.


**EDIT*** I just noticed your using an escalade harness on a 5.3..... That might not work unless you run escalade sensors and I believe the reluctor on the crank is a different pulse ( 48 vs 24 ) so the computer and harness wont match up.

I have the full harness and sensors that match the 5.3.I believe everything is the same as a truck 5.3.

Are you going to wire it up yourself?

I just finished customizing one for a buddy. Took about 9 hours. Its all wired into a fuse block from an 00 Cavalier cuz its nice and small and easy to modify. If you're interested shoot me a pm and we can talk.

Thanks for all the replies,i am going to try and find someone who can sell me a plug and play set-up.I am really not into screwing around with the electric throttle set up and this harness requires alot of work to run a throttle cable set-up.I will be looking for an earlier set up 99-02.
Let me know if anyone wants my harness.

Try Howell, that's where I got mine. Call them up and tell them what your doing and the harness will be made for your application. http://www.howellefi.com/shop/customer/home.php?cat=253
