What I have so far is What ever car you are swaping use the harness from that car. You may need a conversion harness ex: OBD0 to OBD1 according to your motor IE: if you have a obdo crx and a obd1 motor.

If you have a 94 eg OBD1 and a OBD1 H22A1 youse the d16 harness that was in your car. also make sure it is vtec harness if you are running a vtec motor. If not you will have to wire it up.

The key word to search for is FAQ. Like "h22a1 FAQ". It will most likely find what you are looking for or try "write up"

In the H series motors you have to have a chipped P28 or the P13 ECM-ECU. Or whatever ECU is in your car. And that is if you dont go hondata or something.


Uhh... Correct me if I am wrong on any of this.

I typed this up becuase nooo one will tell you jack shit. They will just tell you to do the research becuase they have been doing this for so long and they know what you need to know off top of there head and they think your a dumbass becuase you dont know it to.

Hope that does more good than bad. And if your like me you are just going to have someone fix it for you.
