I have been slowly doing my RB25 swap for a a while now, i have reached the part where most people dread. I got my car as a shell so ive started from scratch, i made my own gauge cluster and switch cluster. the ecu is powered through a switch coming from a fuse block i made, that runs through a relay before power reaches the ecu. my question is what pins do i need to tap into on the ecu to run my car?
