i just recently purchased a 91' accord lx and im gonna be doing the h22a swap in it and im unfamiliar with what exactly i have to do with the harness....will the stock accord harness hook up to the p13 ecu or is there something i have to purchase for the plugs to match? any help would be appreciated b/c this swap already looks like its gonna be a P.I.T.A.........thanks

 

Once the ECU is ODB I it will just plug into the stock harness and then from there you would just have to wire up Vtec solenoid, pressure switch, and knock sensor. If you have an ODB II ECu then you have to get a harness adapter to use it.
