Mark, the function of the tow board is to repeat the rear lights at the 7 pin trailer outlet. That is turn, brake and running lights. The reason for the tow board is to separate the coach lights from trailer outlet so that a problem with the trailer lights will not take out the coach lights.
The tow board has a relay and fuse for each light function signal sent to the 7 pin outlet.
