Power to roof vent


We own a 2002 Georgetown on which the crank-up roof vent had seen better days. I decided to replace it with a Maxxair Maxxfan for the extra circulation that it would offer. When I removed the old roof vent I was pleasantly surprised to find a brown and white wire pair there, together with a 5-wire signal cable and a 110V cable. In essence, it looks like wiring for a roof air conditioner but there are already 2 A/C units there. Can anyone shed light on what these are for? I'd like to use the brown/white pair to power the fan if possible.

Looks like you are wired for 3 air conditioners all right.
Is there 12VDC on those wires all the time?

If you look near the electric panel there should be some unattached wires that are the other end of those wires at the opening. Can't imagine they would be tied in. If there are blanks on the 12 volts fuse side you shopuld be able to attach the brown to the fused side and the white to ground for your 12 volts. You'll need to add a fuse to the board.
