Dan,
Following up on Ed's advice, check your voltage when operating the awning. Mine was only getting about 9V, (12V when not operating) even at supply wire going into awning controller, indicating a poor connection. I picked up a better voltage and ground source by tapping in to the co-pilot chair power. The leads are 12awg and you'll never be operating both awning and chair at the same time. You can easily fish the wires under the carpet and use a screw driver to gently pry up the magazine rack just enough to get them to the awning supply circuit. I took this route because I couldn't locate the sources of the awning ground and power.
