Question Need Help - '05 LS430 Wiring harness Rt Rear panel

Does anyone know the part number of the wiring harness in the Rt Rear panel that connects to the door lock receiver and the oscillator?
Had a leak and the water damage corroded the wiring at the receiver.
Thanks!

Your best bet on finding a part number for the harness will be by calling the dealership. Replacement of this wire harness appears to be very involved. I would start with cleaning the corroded contacts, and if that does not work, the next step is to replace the corroded connectors. I would definitely stay away from extracting the existing harness and then installing new replacement harness. Part number for connectors are listed below...

Thanks for the reply and the diagram. A little difficult to tell but I'm looking at the connectors in the N5-7 area. There are two modules mounted on the rear next to the right taillight, I need the connectors to those modules, then I can splice them in to the existing harness. The reason I asked for the harness PN was so that I could track down the connector PNs.

The leak was at a trunk rivet that slowly took out the taillight, the nav unit, the receiver and the wiring. The taillight and the receiver were easy to acquire, and I found a place in Van Nuys (Hi-Tech Electronics) that completely refurbed the nav unit and replaced the motherboard for only $600, a whole lot better than the $6k the dealer wanted. Now I'm down to those final connectors to get my smartkey working again.

Here are sketches of N4 thru N7. Are they the ones you're asking?
