I'm converting to a reprogramed P28 (92-95 Civic EX/SI). Should I use the ECU wiring diagram for the 25-95 Civic or should I use the diagram for the 00+ Integra GSR. Any help is greatly appreciated!

P.S. anybody do this with a P28 and 2000 GSR? Any problems (CEL or other)

 

it just depends on near what plugs you are gonna tap into near. if you are running an obd2 to obd1 harness you can do it before the obd1 plugs or before the obd2 plugs. it really doesnt matter. it will work fine no matter which way, and no one really ever gets a cel from a vafc install.

 

Big Teggie,

I thought it did matter because the pinouts are different on the P28 compared with my stock ECU. Unless you're saying I use the new harness in conjuction (daisy chained) with my stock harness? Is this the case...Do I still retain use of my stock harness?

 

some pinouts are different but you wont be using them. The vtec, pressure, ground power, etc. is all the same on a p28 and p72.
