i was wanting to know if a 92 civic wiring harness would work with H22 ecu and the motor.....?

 

a lil help anybody....?

 

engine side - many connectors will need to be changed over, use the harness from the civic, and connectors from the H22 harness. (injectors alternator etc.)

car side - just plug in the ECU directly

of course that is with a 92-96 OBD1 H22

 

so the h22 ecu will plug in directly with the d15 wiring harness....all i have to do is plug in vtec

 

The ecu would plug into the d15 harness,but either way,for that ecu to work,ur gonna need to wire up vtec,vtec pressure sensor,and the knock sensor,egr valve,egr solenoid...If u can get a hold of a ex,si p28 ecu all u will have to just worry about the vtec sensors.I would suggest getting some saturated injectors like the ones that came in the 99 prelude i believe.Or get some RC's.If u get some rc's slightly higher fuel output like some 440's,u can get away with using a stock p28 program for a while.How do i know this?cuz i have done it before.A tad rich,but better a lil rich than lean.Later on u can get a remap or hondata done to tighten up the fuel curve.U can however hack up ur stock harness and cut off the prelude fuel injector plugs and splice them onto ur stock harness and use the peak hold prelude injectors but sometimes it will run funny.And even if u use the resistor box,it will still run weird at higher rpms.Hope this helps
