It takes less than 5 minutes to convert your Military 12PIN wiring harness into a standard 7 PIN connection with a wiring harness in hand.
The wiring hardness Expedition Supply sells are plug-n-play ready so no cutting, splicing, or soldering needed. Others may sell them, but may not be plug-n-play. In this video we converted the connection from a Military Heavy Tactical M1102/1 Trailer.
The junction box may be in a different place and the numbering different depending on the year and model. For this video we did not remove the 12 PIN wiring harness. We tucked it away, under the trailer frame, for future use.
