I am installing an ATU300 in a 4440. I have a greenstar harness and the ATU harness. I assume I have to come up with a connector to patch in 12 volt power directly from the battery. It looks like I will connect the power to the ATU harness, and then the greenstar harness will pull power off of the ATU harness when I plug it in.
