Was wiping down under hood (Bonnet) and discovered this plug (sensor) at rear of the right bank . It was 5"-6" long and went back into the Rt. harness near a 3-way split. The coil or injector harness also comes out here. It has Red and Black wires and was tucked down at rear with nothing attached. Appears to have 2 spherical prongs at terminations point. This is a 4.2L EARLY Production date. The Harness diagram is inconclusive. Anyone got additional info?

 

Don't apply for a position as a photographer Kelly. I think I have the same plug on my 06 and it doesn't appear to go anywhere.

 

#2 pic. not close up

Sorry RJ, hope this is not grainy. I tried a close up but poor quality. 1st glance appeared the wires was baked, but they are just small gauge wires. I put a small plastic corrugated wire sheath around them and re-hid behind the other lines. No error codes so looks like all is well.
