We found the brake light switch tap on the panel, and
used a standard 1/4" spade connector to connect it (red
wire is from brake controller)
Get a test light and test all the un-used pins on this
panel, looking for the one that lights up when you press
the brake pedal. If you can not find any that light, you
will forced to find the brake light switch wire under
the dash. The brake light switch is very hard to reach,
but with a probe tester, look for a wire under the dash
that lights with the brake lights. I " THINK " (from
memory), you are looking for a small gauge white wire.
Tap into the wire for the brake light feed (red wire on
most controllers)
We used this stud (powered by the 30 amp green fuse) to
power the brake controller, and supply power to the 12
Volt power terminal on the trailer plug. This truck did
not have wire ran to the back, so we used our 2
conductor brake wire and ran it ourself. Drilled a small
3/8" hole in a rubber plug in the fire wall to run the
wire to the brake controller under the dash.
