Installing a brake control unit isn't very difficult. This task is made even easier if your tow vehicle is a late model and comes with a 7 Way Connector as part of the towing package. Nissan Titans with the "Big Tow" Package will have the wire connectors in place.
In this case, installation is as simple as mounting the brake controller in a convenient, easy to reach place, usually under the dash, just above your right leg and connecting the wires from the brake control to the wiring harness and then plugging the harness into the harness located under the dash.
On Nissan Titan trucks, with the tow package, the factory provided a plug under the dash to connect the brake controller. On the trucks I have done, it is a plug, located up in the dash, just above park brake, up under the dash. You must have the factory plug harness to plug in.
The connector is taped to a wire harness to the left of the steering column. The easy way to get to it is to remove the plastic trim below the steering column. There are two phillip head screws at the bottom. Remove those and the panel will then snap off. You can then get to the connector.
