3 light to 2 light power converter / PM32
       PM32

Power Converter
Designed to draw power from the tow vehicle's battery, eliminating the excess draw on the tow vehicle's turn/stop/running light circuits. This is very important for newer vehicles. Converts a 3 wire (separate brake light) system to tow a trailer with a 2 wire system (brake and turn combined). Can be used as a power module (2 to 2) by not using the brake wire.

STANDARD ELECTRICAL CONNECTOR WIRING DIAGRAMS
Standard wiring pictured below as viewed from the rear of connector (where wires attach). 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. With the 6-way plugs, the 12V wire and electric brake wire may be reversed to accommodate trailer (especially horse trailers.)

4-Way Plug


5-Way Plug


 
6-Way Plug Car End
(View from back of plug where wires attach.)

 Screw Hole

 
6-Way Plug Trailer End
(View from back of plug where wires attach.)

 Screw Hole


Warning: It is necessary to use an electrical tester to establish proper match of vehicle's wiring to trailer's wiring. Failure to do so may cause damage.

*Due to the wide variety of applications on the 7 way round plug, it is necessary to take extra care in matching the vehicle's wiring to the trailer's wiring.
