The wiring inside the bed on the ballast tray is it done or do you need some help with that? As there are 2 hanesses on each side of the tray along with the timer console control cable on the right side and the main power cable comes in from the rear and hooks onto the terminal line at the front left corner of the tray You willsee a large brown wire, one large blue wire and a green, ( green is ground, hots go onto the blue and brown either - or doesn't matter.) You should have a t-max connection in there if not let me know.
