Check the SR engine subforum out and try searching as well. There is a sticky at the top of the SR page that has links in it to wiring how to's and install advice. There should also be threads about S14 and S15 motors into the S13 chassis. S15 motor is a bit different and will require mods to fit. The S13 and S14 SR's fit into the S13 chassis, but need harness re-wiring to work. You use the SR ECU and SR harnesses for the motors, but have to re-wire some stuff to hook everything up. 89-90 tach will have to be replaced. The SR can't drive it properly. you'll need a 91-94 tach for it to work (this is for an S13 SR into the 89-90 chassis). Anyway, do some searching and you'll find what you need.
