98 o2 Wireing?
Before I get flamed, I did search and found nothing to help with this problem.
98 GMC 1/2 Ton with a 350/4L80E and the 350 harness and ECM out of a 98 3/4 Ton. every thing is fine except it keeps throwing PO140 rear O2 no activity.
The rear O2 is new. The harness at the back of the transmission has six wires, that connects to a sub harness that runs across the tranny cross member to the O2 (post Cat) that has four does anyone have the pin out of these?
The sub harness is from the 1/2 ton.
Thanks A.J.
