Hello,

I'm looking for some advice on locating the front gray triangle shaped O2 sensors on the 2002 truck 6.0 C2 block to wire to a standalone fuse box. I've located the pink wiring for the rear O2 sensors on E8 per the diagram but it also says look in slot D8 for the front O2 sensors. Ive touched ever pink wire for continuity for the front O2's but it only buzzes on the pinks for the rear O2's. I have an untouched harness but there is nothing wired to the D8 slot theres not even a metal terminal in the slot. Are the front O2's just powered through the PCM? All help is appreciated thanks.

My 01 has the front 02 sensors powered by the ECM. Check pin 74 for a green/white wire see diagram in link. If its there then they are powered by the ECM. Assuming you have the red/blue ECM.

Yes I have red and blue connectors. Just made it to work but I will definitely check that and report back

Yes I have green/white on pin 74 red connector plus continuity buzz? So I can just fuse all my pinks to standalone and be good to go without worrying about front O2's?
