Hi Pete,
Thanks very much. I was asking for the 12 Pin NATO wiring harness plug pin configuration, but I have since gotten the info I needed.
I pulled the pin letter circuit designation from the M416 TM, and also contacted the Manufacturer. I am having the Female tow vehicle socket end made with the circuit letters I wanted to use already wired up.
I intend to make an adapter to allow me to tow my M101 CDN2 trailer behind my H3, and then when I get an 'M' series MV, I will be able to connect the Nato plug with out any issues.
