ok i know that this is probably the wrong place to put this post but i need help from anyone that can offer it. so im doing a tpi swap to my 90rs. harness is diff so i order one from summit. well now i need an ecm i didnt know that they were diff, well i knew but i didnt know they were that diff. so now i need an ecm and ive called all the salvage places near by and none have ecms. i called thirdgen rescouces and they dont have any ecms either. so right now im up a creek. ive been with out a car for threee weeks now. if anyone can help me locate an ecm i would be very grateful. by the way i have a harness and ecm out of a 87 tpi
and i have a harness and ecm out of a 90rs. i also called local part stores and they have the ecms with out proms and i know i need that. and if i purchase an ecm from them where can i get an inexpesive prom for a 90 tpi camaro. lol. well thanks to anyone that can help me.

 

Last time I looked, a TPI harness in the SD cars plugged into the dash exactly the same as how the TBI harness plugged in, so IMHO, you should really get a factory harness. Probably will be cheaper in the long run to get a TPI setup from 90 - 92 instead of piecing one together.
