Where is the wiring to connect an electric brake controller on a ford 450 RV van chassis?

On a Ford F-450 RV van chassis, the wiring to connect an electric brake controller is typically found under the dashboard, near the steering column. Look for a wiring harness that includes a connector specifically for the brake controller, often labeled or color-coded. Additionally, you may find a 12-pin connector under the dash that connects to the brake controller, which usually requires a power connection and ground. Always refer to the owner's manual or a specific wiring diagram for your model year for precise locations and instructions.
