OK so here the situation i have a obd 1 to obd 2 (1996) harness and i cut the lambada 1 ( o2 input ) so i could run my wideband o2 to my AEM EMS. I am now trying to go back to the stock ecu for emission testing but i dont know which pin out it is on the OBD 2 side the wire that was cut on the OBD 1 side was pin D14 i need to know which pin it goes to on the OBD 2 side. Also i need to know which of the two connectors on the engine harness is for the primary o2 sensor since OBD1 ecu dont use secondary ones.

Thanks
