    the harness wont work because you have a non obd vehicle you need a si wiring harness and ecu and you will be fine

    daidilus, read a little more carefully, the tranny is from a 92 LS... meaning it's already Cable....

    u will also need obd0 intjectors to complete the obd1-obd0 swap, i also suggest DO NOT USE THE SI ECU, ITS MADE FOR A 1.6L SOHC ENGINE NOT A 1.8L DOHC ENGINE. damnit people use the ECU intended for the motor, since u cant use an obd1 LS ecu , USE THE OBD0 LS ecu!!!

    My buddy wants to do this swap on a 90 si hatch.
