I have a problem with wiring ! I bought a Prelude H22a engine with all wires and ECU from that car. The engine is instaled i my 93HB. All wires from engine to ECU are connected ,but I dont know how to connect wires from ECU to (switch) equipment in my car (lights,windows,horn etc.) Maybe somebody know how to do it ,have some pics of this work or something ?

Thanks for any help !

 

is this an OBD2 harness?....anyways, best is to use your stock harness, you'll have to extend a few plugs and add vtec solenoid, vtec pressure switch, knock sensor, EGR and IAB's. use the plugs and length of wires from the prelude harness.

 

I dont have OBD2 harnes what am I do ?

 

Need more info as what u need help with, is the motor obd1?
If so like the other poster posted extend a few plugs add a couple wires run them to your ecu, and thats it. Lights windows and horn I believe run on a different harness, has nothing to do with the motor harness.

 

I had d13b2 motor... i dont thing that other harness will fix into the ecu gap.

 

dont use the prelude harness, its easier to use youu stock harness that was on your old motor, just take it off(make sure u label where each plug goes) then put it on the h22 motor, your going to have to extend several wires, plus add the the wires for vtec vtec solrnoid etc. and run them to the ecu., and might have to change a plug or too. Look in the faq, all the info is there.

 

ok I will try ,thanks for help
