For those that have done the vortec 5.7 conversion, can you help me. I have a 97 vortec with a 700r4. Any help would be greatly appreciated!!!

Hey Try Painless Wiring im sure they have A kit

But, Unless u go with carb wont u have to have the 'puter?




BTW Norman? Thats cool i live in purcell..........


And WWW.LWM.CC

I have the computer and all of the wiring harness. i just need to know what to keep and where to put it. last time i checked painless doesnt offer a kit for the vortec

I believe Centech and Howell sell a wiring kit for the Vortec, but they are very proud of them ($600). I'm swaping a Vortec into a CJ using an NV tranny. I splurged for the $12 Haynes book. It seens about 80% accurate as far as color codes for my motor. As far as I can tell, there are only a handful of wires that need to be spliced from the Vortec harness to the CJ harness. The rest of the Vortec spagetti looks like it can remain unchanged. I think I'll reduce the # of O2 sensors from 4 to 1. Project still underway, so no definite answers yet!

These guys make the harness you need speedscenewiring.com
