im currently running a d16y8 swapped in a 00 ek with 00 civic ex wire harness with a p2p obd2 ecu. when i bought the car it was running like **** because the wire harnesses were spliced and taped together dont kno from what car for what motor harness. i searched and found a 00 ex wire harness of craigslist. everything went on perfectly it was running great and alot better but i couldnt find the secondary o2 sensor outlet which made my engine check turn on. i looked and couldnt find the sencondary o2 outlet. i looked at a my friends em1 and both o2 outlets came out one way on the wire harness? anyone know how and where i can splice into the harnesses and add the secondary o2 sensor outlet so the engine check can turn off? thanks ht will try to have pics up tmrw!

 

anyone need help asap emissions comin up fast....

 

plugs in behind your dash.. like directly behind the cup holders

 

You need to find a pinout of the ECU and wire from there. That will be the easiest and best way to do it instead of trying to hunt down the connector and wires from the harness.
