05 durango sunroof wiring

Afternoon,

I want to install an auto close to the sunroof in my 05 Durango (I keep leaving it open and I am tired of wiping snow and rain up..) so every time the vehicle is locked it closes the sunroof.

I am hopng the community can assist in two questions:1. I have the wires at the switch, however the unit (CS-5501 Model 72) states to "prefferably" go to the motor wires, NOT the switch. Is this do to the resistance to shut the CS-5501 down when closed?  I know the factory switch kills upon closing so If I use the (-) wire at the switch will the CS-5501 just keep on' going and kill the battery? Is the switch low volatage causing the need to go to the motor wires? 2. If I have to use the motor wires, does anyone know what and or where they may be other than at the motor itself? Since the Durango has the factory DVD system I prefer to not have to pull everything down to get to the motor, I am hoping the wires are accessable else where and I can test them there. Headliners can be a pain to get back up...Let me know your thoughts - Thanks in advance.

is it a factory roof or an aftermarket roof? In most cases the motor wires jump directley to the brain an the brain is most likely next to the motor1 12" mtx 9500 4ohm dvc 1 8100d and 1 1501d almost loud enough to cover the sounds of my car dying.
