I have a 1989 Mazda Rx-7 turbo 2 that has a blown engine. My goal for this car is to be a daily driver and a weekend drifter. I was looking through all of the available swaps for this car and I've come to the conclusion that I want to install a SR20DET, but the one thing I'm stuck on is the wiring, how would I go about wiring the ECU and retain all gauges inside the Rx-7?
