Brake Controller Wiring?

[Old Scout]

Anyone know if there is a spare wire running back to the hitch plug--need to support an electric trailer brake? We have an early 2003 with a 6-pin plug and one pin is designated as a spare, according to the WRV wiring diagram. Am thinking I'll have to run a separate wire from the cockpit back to the hitch plug for the trailer brake?

There are two spare wires in the harness on my 2000. They run from the front cap just above the gen set back to the left side of the engine near the frame rail. They are marked spare 1 & 2. I do not know specifically about the 2003. Call WRV service center if you cannot locate them yourself.
