Not shown, but we found a easy spot on a metal bracket and grounded the ground wire under the dash with a sheet metal screw.
We tapped into the WHITE wire with the TAN tracer for the brake light signal (red wire on the controller). Test to be sure, it must power on when the brake pedal is pushed. (See picture above, under the dash)
Battery feed was taken from the battery feed wire for the trailer plug (under the hood)
The ground wire (WHITE) was grounded under the dash
