Roadmaster Sterling All Terrain User Manual

The Sterling All Terrain tow bar comes equipped with a

fully-wired motorhome-to-towed vehicle electrical cord —
simply plug the cord into the sockets on the motorhome
and the towed vehicle.

If you should need to rewire the plugs and sockets,

follow the instructions below for a four-wire system, or the
instructions on pages 14 and 15 for a six-wire system.

1. Insert the end of the electrical cord through one of the

cable guides.

2. Wire the plug to match your vehicle, or follow Figure

existing four-wire harness.

2. Loosen the set screw at the back of the socket, and

push the inner connector out the front. Now, run the four-
wire electrical cord through the back of the housing.

3. Loosen all of the set screws on the side of the sock-

et, and connect the wires to the back of the socket, as
