Where to get Harness for Park/Neutral switch? - Toyota Nation Forum : Toyota Car and Truck Forums

Its a 99 Camry, I have the P1780 Park/Neutral switch malfunction. I checked every wire in the trunk, they're all fine. I found the plug for the switch itself was all melted and green inside. With the harness unplugged, the issues go away. I've called everywhere I can think of (dealer and countless junk yards) and noone has just the harness. Does anyone have any clue where I can pick one of these up? Thanks.

Park Neutral Switch in the trunk?

I'm confused. I'm pretty sure that the NSS is located on the front of the transmission.

If the plug is melted, I would guess that one of the wires are shorted somewhere causing the fault. Or the Switch itself is faulty causing it to short out.

check the NSS first, then check the harness.

Yes, I do mean the NSS on the transmission. with the NSS plugged in the R indicator blinks opposite the blinkers while flashing (both of them). Also, the clock and dash lights don't work, I tested the harness for the clock and its not getting a ground. I'm going to test the switch today or tomorrow, i'm really hoping its not a short in the dash somewhere.
