TYPICAL TRAILER WIRING
NOTE: Not all trailers/vehicles are wired to this standard. The use of an electrical circuit
tester is necessary to ensure proper match of vehicle’s wiring to trailer’s wiring. On the
6 way plugs, the 12V wire and electric brake wire may be reversed on some trailers
(particularly horse trailers).
