i'm going to get an f20b and it comes with the harness and ecu, what will i have to do to hook it up to my sub harness? i know i'll need a conversion harness on the ecu side but will the plugs mate up on the engine bay side? anyone know?

 

nvm i just looked at the pics of it and it has the harness all the way to the ecu. thanks anyways lol

 

so how are you gonna do this? run obd2 in your obd1 car?
you know if you ever want to get a tune you will have to swap back to obd1 right?
