I just spent the last hour installing the new FoMoCo trailer plug assembly onto Henry, I was getting tired of changing the trailer plug every year cause the aftermarket ones rot out from the liquid salt PA uses on the roads. 130.00 was a bit expensive but I think it will be worth it! Any way, I want to install another in the toolbox in the bed for the goose. Has anyone already done this and if so post up your pics. Did you make a new harness from the rear up to the box or splice into the harness along the frame rail? I think I am going to make a harness from the rear, also I can then hook all the LEDs to the new aux harness rather then run them from different locals all over the truck. That is when I replace the LEDs with new.
