Thanks, Pat. Can you you think of any reason not to use the main batteries in the trailer to operate the break away emergency brakes? Seems too obvious to be sensible. Jon.

Jon,

The break away switch must be wired to the trailer's battery !!If the unit were to "break away" where else would the power for the brakes come from?( If  the trailer were to separate from tow rig.) Do you have a good break away  switch mounted on the tongue at this time? If not, use a good quality switch and mount it where the pull wire has the most direct route to a hooking location on the hitch platform. The pull wire needs to be the proper length to where it won't pull out when making sharp turns, but not so long as to make it
ineffective. This is very important safety equipment as far as I'm concerned.
