Anybody know how to wire Bosch universal oxygen sensors up to a 02 5.3 harness? Ive got them Hooked up so the pink wire and black wires from the engine harness go to the two white wires on the sensor. And then the purple wire or hi signal to the pcm is hooked to the black sensor wire (this was described by Bosch as the signal wire). Then the gray wire from the sensor is supposedly ground but the remaining wire from the engine harness is the tan wire which is the low signal wire? Is this the correct way...?
