Engine PCM has no pins for position 47 and 50, so where exactly is the H02 S12 wiring (WH-BK) routed? How can I check where the ground fault is if there is no connection at the PCM that is shown on the wiring diagrams.

Hello, I've been looking through the diagrams as well, and you're right it's confusing. Are you sure the wire isn't black/white? Because I found this generic electronic module, it's another type of PCM. Like a slave module I think. It has black/white going to it(power) and coming out black/white ground. Update: So, this ECM has 3 different connectors, here's all 3. C175T is the one you need. Pin 48 and 48 are your oxygen sensor heater circuits.
