I just installed these.
I reversed the harness and went down the passenger side A pillar. I connected to the B1 brown/white wire behind the glovebox. Then used Aux 6 for the power.
Very simple and works great.
It only works with the Aux switch and is not connected to the regular dome lights.
FFS Ford, let me control my own vehicle. How am I supposed to remember the only mode 2H RELD above 25mph is Baja? Are we supposed to test all modes and 4wd combinations weekly to learn them and remember them?
