Reverse Wire for backup cam location in cab?

[svdsinner]

I'm installing a wireless backup cam onto my horse trailer. The in-cab monitor is looking for +12V igntiion, GND and a Green 12V reversee light wire. The first two are easy to locate, but I've got no clue where to look for a reverse light wire that I can splice.

I'm installing the monitor on the top of the center of the dashboard, just above the 12V power outlet, if it matters.

Where is a reverse light wire I can tap?

I would tap in at the reverse light at back of vehicle.

On your transmission neutral safety switch there is a 12v power and a reverse headlight feed. When the truck is put in reverse it closes the circuit and sends 12v to the reverse lights. If you can get a wire down to the transmission you could tap that. It’s a 3 pin plug below the gear shift selector.

Where is this at? Under the cab on the transmission housing? Behind the dash somewhere along the shifter linkages? Sorry if I'm dense.

The plug I’m talking about is on your transmission, driver side about halfway down. There may be some other place to tap on inside the cab, this is just the place I know will definitely work
