How do you use the integra engine harness for the B18A1 in your CRX. Also where is the oxygen sensor plug and the EGR plug? I have the B18A1 harness and the opposite plugs to go with it.I wanna make all my engine connections match up and full signals to the ECU. how to do so??

 

use ur stock harness not the ls harness and if u have dual oint ull have to convert to multi point.

 

I have a B18A1 engine in it. I have no EGR plug and i can't find the O2 Sensor plug. So i wanted to use the B18 harness to use all the proper plugs for the engine.

 

so its in and theres a egr valve, so uyr motors an auto and u dont need that with a pr4 ecu. and the o2 plug is 1 wire close to the head water temp sensor. well u could i bet ull have to rewire a little bit of it. i cant remeber if thats the reason to use ur stock crx harness.

 

you use your stock harness because it will plug into the car as the other ones will not, but you have rewire the injector part for multi, add the resistor box , add CYP sensor to the distributor and repin it,reverse 1 & 3 on the TPS plug , extend the EVAC valve wires. then run the 2 injector & 2 CYP sensor wires to the ECU.

 

^^^ He's outlined everything you need to do. For your O2 plug you can get a wiring diagram for that ECU your using and just run new wires from ecu out to the plug.
