Could not find this posted anywhere so I thought I would review how I did it.
One could just cut the military plug off and spice in something else. However, I wanted to keep the trailer harness intact, so I chose to build an adapter.
First we look at the stock FJ setup, a standard 4 pin connector. You will need to buy a 4 pin male trailer connector that fits this, about $4 for me.
The trailer sports a 12 pin connector. Don't bother trying to find an adapter at the hardware store, they will just look at you funny if you ask.
I got a military vehicle trailer receptacle from Saturn Surplus. TRLRPLUG It ran me $22.50. The plug I got did not have any attached wires. What you see here is after I connected it to the 4-pin male:
The wiring basics I used:
Civilian......Military.....Function
Green........J.............RH stop and turn
Yellow.......B.............LH stop and turn
Brown........E............Tail/Running lights
White........D & L.......Ground
I used a scrap piece of aluminum to make a bracket and sealed up the back side with liquid electrical tape:
Installed it on the FJ using the same bolt the stock setup uses:
This allows me to tow either military or 4 pin civilian applications. Total cost was about 1/2 hour and $30.
