Sorry for the late reply, pictures in the daytime...
The Screen on the dash. I ran the wire towards the windshield, and since I have a dash cover I ran the wire under the dash cover and out the bottom left corner seen in the next picture with the controller

The wire from the controller goes behind the front of the dash, and runs out in the next picture.

The wire on the left is the controller wire and the bigger wire on the right is the wired adapter.

This is just a shot up behind the dash the silver box is the adaptor.

Those run to where I keep the brain. hehe

Secret agent man....

Power you say. Well it came with a adapter for a DC so I ran the power cable from the brain to an extra DC outlet I had under my seat. You can also hardwire it if you wish.
