Thread: P0135 need pcm pin out for 5.3L to rewire

I have replaced sensor twice.
Replaced pigtail to o2 sensor 1.
I have 12v power to harness.

Any other ideas besides replacing 3 wires back to the pcm? Does anyone have the pin out diagram and with wire color codes and descriptions for the 3 wires back to the pcm. Been trying to pull wires through main harness which is a chore in it self not to break any wires going back to PCM.

Solved, found wires receiving magnetic field through main harness. Pulled wires out and wrapped in electrical tape and separated in new wire loom with just the alternator cable. Problem solved

It was all entangled so I cut wires at pcm and butt connected with heat shrink connectors
