My car is a 1987 Nissan Pulsar NX SE With a CA 1.6 DOHC FWD 5SPD. I just purchased A JDM SR20DET GTiR engine I was told it came from a 1993-1994 2.0 Nissan Sentra. I need to find out which wiring harness I will need to purchase for this swap. Can any one help?

you will probably need the entire engine control unit and engine wiring harness from the SR20
