Ill take some pics of my met pro. Its been a couple months, but i dont remember having to connect anything to the right hand power area. My game was pre wired with connectors right where the shaker kit needed them. All on left side of machine.
The only tricky connection i had was finding the connector way back in the cab to connect to the harness that goes up to the back box. That is one of the last steps. Did you run a wire (i think it was brown) along the bottom of the cab and plug it into the harness in the bundle of wires laying on the floor of the cab in the back?
