TYPICAL TRAILER WIRING
NOTE: The standard wiring pictured in g. 4 is viewed from the front of the connector.
Not all trailers/vehicles are wired to this standard. The use of an electrical circuit tester is
necessary to ensure proper match of a vehicle’s wiring to a trailer’s wiring. On the 6-way
plugs, the 12V wire and electric brake wire may be reversed on some trailers (particularly
horse trailers).

TECHNICAL TIPS
• Never assume a battery is fully charged. Small batteries are especially prone to failure if
left discharged. Always verify your battery is charged to at least 12.2 volts before using.
• Most electric problems occur at the plug. Always make sure the pins are clean before
assuming something is wrong with the trailer.
• The Power LED will illuminate (even in the OFF position) when the tester is connected to
a trailer that has its own on-board battery supply. This indicates that the tester
recognizes voltage coming back from the trailer.
• As a best practice, limit the time engaging trailer electric brakes with this tool. Electric
brake magnets get very hot and are not intended to be left on for extended
periods of time.
