I have the manual with the wiring and the problem is the wire for the pump is not in the bulkhead. The cavity is empty. I guess they saved about .02 by not putting a wire in there.
So if you wanted to convert over to automatic you would have to run a new wire, do you think the automatic ones do go through the bulk head, what pin is used on the bulk head to connect the pump to and then go back to the switch.
