got a d16a with the cut engine harness....does it matter what yellow/ black wires to what yellow/black wires i connect to from the car harness to the engine harness? for example i have 2 yellow /black wires left on the driver side plug - they are for the american o2 sensor i have been told - but the rest of the yellow/black wires i have just hooked up to other yellow/black wires.....does this make a difference? like in injector pulse or anything - thanks a ton
