M6 Reverse lamp wiring I am wiring up my reverse lamp switch and I wanted some conformation before I do it. Wiring Diagram says it receives power from circuit 141 at connector C220 pin G in the interior passenger kick pannel and signal goes back out circuit 24 at the same connector pin H. I do not see circuit 141 any where else on the engine harness wiring diagram so what im thinking is that power is supplied from the dash harness and goes uninterrupted or tied into anything else to the sensor and back out the same connector. Is this correct?

The circuit gets power via the Turn B/U fuse in the dash, goes out to the backup lamp switch on the transmission through connector C220 and then returns into the interior through the same connector. It then routes down the left side of the vehicle through connector C400 in the left rear cargo area to the tail lights. There are other things that share that power source (signals, DRL, etc.) but the backup light circuit is independent beyond that.
