For your 2008 Jeep Commander, the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles, part # HM56205 is what you are looking for. This harness easily plugs into your vehicle's existing wiring, located behind your Jeep's tail light assemblies. No cutting, tapping, or splicing is required. If your motorhome uses a standard 7-way connector, you can use coiled adapter # 787196 to connect to the 4-Way on # HM56205.

With this harness hooked up for flat towing, your Jeep's lighting system will operate as a combined (2-wire) system. The brake and turn signals sent by your motorhome (with a 2-wire system) to your towed car (with a 3-wire system) will be carried on a single wire.

You'll also need to install a brake light relay # RM-88400 when using a supplemental braking system. Otherwise, the brake signal from your towed car will override the turn signal sent by your RV when you slow down to make turns, creating a potential hazard.
