We found a easy spot on the firewall 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
A small hole was drilled in the fuse box for the power wire to pass through, then directly to the circuit breaker. A direct battery feed could have been used also.
The inside panels just pop in and out, no screws.
The location shown allows us to drill through and not hit the main box frame or the hitch. This van had the 3 row seating that folded into to the floor. We drilled right at the edge of the seal well.
