Ok, I have a '94 GSR shell, I'm trying to use the '94 engine harness on a newer '98 GSR motor. I changed out the injectors, distributor, and alternator, but it appears that I have left over plugs....like 3 actually. One of the sensors won't plug up, one that goes right under the 2nd runner on the IM. Can anyone help? TIA

 

List the wire colors on the plugs in question so somebody can look them up on a diagram and give you the correct sensor or actuator that it plugs into.

I know you won't need to plug in the CKF sensor on the oil pump, but I can't think what the other two might be.

 

You mean that plug will be left over from the harness? And it won't throw code? I'll have to wait til I get off work before I can look again. Thanks

 

It depends on whether you're gonna use an OBD-1 or OBD-2 ECU. Since you already swapped to using the OBD-1 injectors, distributor, alternator, and wiring harness, you should be using an OBD-1 ECU....which won't look for a CKF input sensor.

Yeah, I'm using an OBD1 ECU. Right now, the only code I'm throwing is o2 sensor I think, and that's because I forgot to unplug it when I pulled the motor out so all the wires came off the plug Anyways, thanks Ill check up on it again later.
