Question:

What wire is installed on RV to tow trailer

Expert Reply:

I'm assuming you're wanting to know how to wire your RV to tow a trailer, is that correct?

This will depend on which trailer connector your trailer uses. If the trailer uses a simple 4-pole connector like part # 18004, you would install a 4-pole on the RV.

If your RV uses a separate bulb behind an amber colored lens for the turn signals, you'll need to use a 4-pole with a converter, like part # C59236. If your RV uses the same bulb for brake lights and turn signals, with a red lens you'd just use the connector without a converter, part # 18252.

In either case, you'd wire the connector directly into the existing taillight circuits.

If the trailer uses a 7-way connector (see the linked article), and you're just needing lights you'd first install the 4-pole as mentioned above. You'd then use an adapter like part # 37185 which would plug into the 4-pole and provide you lighting circuits for the trailer. You'd ground the white wire, and if your trailer doesn't have brakes, you'd be done at that point.

If your trailer has brakes and you'd want them to actuate, you'll need to install a brake controller using our Brake Controller Install Kit, part # ETBC7, which includes the adapter mentioned above.
For a brake controller, I'd recommend the Tekonsha Primus, part # TK90160. The Primus is a proportional brake controller, which means the trailer brakes would apply at the same rate as those of the RV for safe, predictable braking. The # ETBC7 kit contains everything needed to install a brake controller, but due to the extended length of an RV versus that of a car, truck or SUV, you'll need some extra wire, it's sold by the foot as part # 10-2-1.

I'll link you to some FAQ articles and install videos that I hope you'll find helpful.
