1992 WB40 Spare wire from front to back?

[mbrund]

Is there a spare wire that runs from the front to the back of a 1992
WB40 that I can use for my brake controller?

I have a US Gear D-Celerator brake system that needs one wire to tell
the system in the toad to apply the brake, and another to keep the
battery charged. I am not worried about the one for charging as I can
grab that right off the back of the coach, but did not want to have to
run a wire all the way from the front to the back if a spare already
exists for that.
