The port is located in the vehicle's black electric junction box underneath the dashboard, left of the steering column and just above the carpet. You will have to remove the cover. The brake controller adapter is plugged into the second slot from the left on the top row.
The brake control wiring adapter is used to simplify the electric brake controller installation. The 4 wires on the adapter are butt-connected to the 4 wires coming out of the electric brake controller. The harness is then plugged in to a port under the dash. All the wires for the brake controller have already been run from the back of the vehicle to that plug. If your vehicle does not have the factory installed 7-way, a trailer connector will be required to connect to the round plug underneath the back of the vehicle.
