I have a 1990 camaro rs with a slug 305 tbi in it i just picked up an 89 iroc tpi 350, i want to transplant the motor and transmission into my 90, my wiring question is can i unplug both the wiring harness on the drivers side firewall under teh hood and the passenger side harness under the dash and plug in the tpi harness or do i need to modify anything to get these to fit.

 

i have wondered the same thing for quite awhile. Come on guys, help him out

 

I have checked and the pin outs on the two plugs are different, but i was wondering if i could seperate the tpi harness from the accesory harness, this way i would be able to leave my stock accesory harness alone, the only problem im going to run into is the ecm fuse the fan fuse the injector 1 fuse and the injector 2 fuse. does anyone know the wire colors for these and if they are the same from tbi to tpi?
