Installing 7-way Trailer Connector and Brake Controller on 1995 Cadillac Fleetwood

We do indeed have an adapter that will convert a 4 or a 5-pole connector to a 7-way, part # 37185.

However, your travel trailer will likely have electric brakes, and to actuate them you'll need to install a brake controller like the Tekonsha Primus, part # TK90160. To install the controller, we offer an installation kit, part # ETBC7. The kit incudes everything needed to install a controller, including the 37185 adapter I mentioned above.

I'll link you to the instructions for the install kit so you can look them over. I'll also link you to a video showing the kit being used to install a brake controller on a Chevy Silverado. Although the vehicle is different, the actual procedure for installing the controller will be similar on your Fleetwood.

The adapter plugs into your existing trailer connector, and will have 4 additional wires. The white wire will be grounded to the vehicle, and the blue and the black wire will be extended by attaching them to the two wire cable included with the kit. The circuit attached to the blue wire will carry the output from the brake controller, while the circuit attached to the black wire will carry the 12-volt power feed from the vehicle battery. A 40 amp breaker included with the kit will be installed inline on that circuit. The purple wire is usually used for reverse lights. If needed, it will be tapped into the reverse lamp circuit on the vehicle. If it's not needed, the wire can just be bundled up and tucked out of the way.
