Probably too late to help, but I mounted mine at the helm in a pod. I tapped into the power for my radio, but still had to run a line to the main unit which is in the back of one of the aft berths.
The Control unit is on the left, ran the power line thru the pedestal from the pod on the rights side which houses a radio. The line from the control unit to the main computer runs down the pedestal thru a rubber hose. I ran all the electrical lines thru a small rubber hose inside the pedestal so they would not get tangled with the chain steering. It may seem difficult at first for tacking but you only need to hit two buttons to bring the rudder over and after awhile you know which two to hit and you can do it from in front of the pedestal. There is really not much else to play with once you get the unit tuned into your boat. I don't sail by the AP, only use it to help me in maneuvers when I single hand.
