FMTV - Trailer / Civilian electric trailer brakes.

[Mikes Bikes]

Anyone ever tapped into the 12V lugs circled in the picture below? (Looking for a place to power my trailer brakes and trailer battery).

I've already wired the plug to feed the brakes, using the pin at 1:00 o'clock. (Need a 12V source for the brake controller in the cab). Using the center pin for constant 12V to the trailer.

Also: Where is the switch that activates the brake lights, when the pedal is depressed?

The is a black break out box to the left of the steering column with lighting connections in it.

The brake light switch is on the treadle valve.
