I do not appear to have the plug shown above. The 6.7 volts is measured at the license plate light with no bulb in place. Same lead as the tail lights.

The way the wiring is ran, the wire coming out of the fuse box is soldered directly to the lead on the LED tail lights. On the drivers side, there is an extra wire off that solder joint that attaches to the license plate light. I tested power at the fuse and got 14.5 volts, same as I'm getting at the battery and front lights.

I desoldered the single connection and nothing changed. Drove the truck for 20 minutes then tested again. With the truck running I was getting 14.1 volts to the lights (which were working). After it idling for about 3-4 minutes, I was only getting 6.7 volts again.
