Hi guys,
I have 1991 Camaro RS 305 TBI automatic and I can buy from friend complete 1986 Corvette l98 engine with harness and ECM.

Is it possible to do engine swap in my Camaro with C4 harness and ECM, or I need to buy complete engine wiring harness from TPI Camaro with ECM?

I know that it is far away from plug and play swap regarding harness, but just to know if it is possible without tons of modifications?

I am from Europe (Serbia) so there is not much USA cars here and I am familiar with engine electronics, so it is not a big problem to modify C4 harness if it doesn't require a lot of changes and ECM from Camaro. In that case it is better to buy complete Camaro TPI harness and ECM off course.

Thanks a lot in advance.

 

It might be easier to Rework the 1228746 to speed density and use a 1227730 ecm and tune. Or a stand alone painless 6102 and disable vats in the tune using the 86 1227165 Vette ecm.
