Two location options are provided: BH1 (under dash, left of steering column, near emergency brake pedal) or BH3 (under dash, in junction box left of steering column), depending on your vehicle configuration.

Insert the CURT brake control harness connector into the empty vehicle connection point. 3. Ensure the connector is fully inserted with locking tabs in place. 4. Insert the brake control harness's black connector into the brake control's quick plug connector. 5. Secure the harness with the provided cable ties, avoiding any pinch points.
When inserting the brake control harness connector into the vehicle connection point, push it in completely until the locking tabs on the connector engage and lock into place. This ensures a secure electrical connection and prevents the connector from accidentally disconnecting.
Use the cable ties provided in the package to secure the brake control harness in place. When routing and securing the harness, avoid any pinch points that could damage the wiring or connectors.
