PART 8: 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 some trailers with 6-way round plugs, the 12V wire and electric brake wire

may be reversed (particularly horse trailers).
