i have 87 na car with s5 turbo ecu is a n374 trying to use original harness cause one with motor was right hand drive car also body plugs are different . thought i could splice with 374 plugs but pins and wire colors are different can i use a different ecu or are there any adapters out there any help appreciated

 

Why are you using a turbo ecu with an n/a car?

 

Never heard of an adapter as I believe the pin-outs/sensors are different

 

you're in way over your head with this one...its not a plug and play install. should have bought an s4 motor (i assume you are doing a t2 swap)

 

wanted s4 got screwed and got s5 any inexpensive stand alones out there . the engine will idle with na ecu will s4 turbo ecu work with s5 turbo, by the wiring diagrams it would be easier.
