I'm putting a tpi motor into my non-tpi 88 iroc-z. I bought a painless performance wiring kit for the 85-89 maf engines and I'm having trouble installing the harness. Has anyone had any expirence with these harnesses in realtion to what I have to splice into what to get power to the computer and my accessories. I still have the tbi harness which I took out of the car originally. Any help whatsoever will be greatly appreciated.

 

What exactly is the problem you're having?

 

i dont' think the harness i have has any provisions to put power to the ecm. and also i would like any tips on how to go about cutting out my old starting and charging harness from the original tbi harness. i just don't want to cut anyting and be screwed later down the line

 

How much did you pay for the painless harness?? I had my original TBI harness converted to TPI for a service fee. Looks killer and just like stock. If interested go to www.TPIparts.net

 

i paid $325 for it I wasn't aware that could be done if i can send it back id rather do that
