I just swapped my 95 b18c1 into my 93 eg hatchn:yay: , and heres the tough part... i guess. I need some help with the wiring... Can I just use a GSR harness? (the 3 main plugs connect but the eg car harness is missing a little plug that the gsr one has ). So if anyone could help me out I would really apreciate this. Thanx.

Wow very helpful, thanx a lot

 

No problem

 

VTEC, Knock Sensor, IAB. Just add 3 wires and pin them to the ECU :thumbup:

 

So I have to use my civic oem harness? (that sux, because i thing its all spliced up from when they did the ITR swap when past owner had it, anyhow they did a hackjob). What would it take for me to use a obd 1 GSR harness? Is that possible? And what about all those extra sensors and the gsr intake mani?

 

Ok, so I have the 93 canadian made civic, where the gsr harness matches the civic car harness perfectly except one of the 4 gsr plugs has nothing to plug into. It is the smallest plug. So could I just use a gsr harness. Can anyone help me find what that one plug is?

 

because you are 93+ on the chassis, you'll need to wire up VTEC.

On the GSR, you'll need to add a wire for the IAB (intake manifold) and Knock Sensor. That should be it. Everything else is plug and play.

 

im assuming one that just hangs on the passenger side? You dont need that as mine is tucked away.

 

Wait, if I use the gsr engine harness, I would have to add hte vtec wire to the plug on the eg car harness, right? And the other 2 sensors as well, I would have to add to the car harness, since the gsr engine harness already has everything needed for the motor. Correct me if I'm wrong.
