Yep, that is low speed CAN on that truck. BUT the lighting is pretty 
much all directed through relays, especially for the towing harness.
The 4 pin piggybacks the wires for the 7 pin in the same harness.

If the 4 pin hasn't been used a lot they tend to corrode of just inside 
the rear area where the pin sockets enter the rubber. Usually on the 
ground pin (the bare one by itself).
