I have a ZC engine and tranny, but I need the ECU and Harness. Is there another ecu and harness I can substitute it with. Thanks for the help...

 

Most people just use the Si harness and the 88-89 Integra ECU.

For the Si harness, you'll have to repin the plug that goes to the distributor from a 7 pin round plug to separate 5pin (distributor) and 2 pin (cam sensor) plugs.

 

If you also need the distributor and cam angle sensor plugs, you can get them off of an 88 - 89 Integra. Oh yeah, and the ECU from an 88 - 89 Integra 5spd will work, but you will need an ecu case from an 88 - 91 Civic / CRX to bolt it to the floor.
