I recently purchased a 2003 25' Coachman travel trailer. The breakaway switch was crushed on the trailer so I replaced it but I am confused about the power for it. The old one only had 2 black wires coming out of it and going to a white and blue wire on the trailer. Those 2 go into the junction box in the trailer. The new one has 3 wires, blue, white, and black. First, what do I connect the black wire to? And second, it says make sure I disconnect the trailer plug before testing the breakaway. Does that mean it will draw power from my trailer battery?
Yes the breakaway / E brake uses the Trailer battery for power after the 7 pin come out. that is why most states require you to have a charged battery on your trailer.
and yes IF you pull the switch out while hooked to the TV. It can fry your brake controler
