I have an electrical connector on a duramax diesel. It is a large connector near the fuse box. It has a leverlock arm to lock it in place. On the side of it is EPC- PA66, E-4587. It is unplugged and I cannot find where it plugs in. It has a red lining inside of this connector with a hole in the center of this plug. It has quite a few fuses please help identifying where there go.

Fuse # 14 is good. I push it in the fuse box where it belongs, but there is no function. I cannot see the back of the fuse box to see what is going on.
