Pictures & comments of the install and tests...
Regarding the CHMSL, I found a blue wire in the MH harness for that line. I added it to the harness running to the trailer elec connector's center pin, and routed it via the last open lead in the 6 wire umbilical. It would have been nice if Roadmaster included a full 7 wire umbilical, but as their kit terminated the umbilical in a 6 pin connector, I can see where they felt the 7th wire would never be used.
Thus, I now have the standard signal and turn on the lower two tail/brake lights, and full brake lights/CHMSL on the upper two tail/brake lights plus the center high mounted stop light.
