I don’t know how that system works but on the 163 the light controller I
installed senses the vehicle lights then powers the trailer lights
independently with separate power. It doesn’t care what is being powered.

I have always heard and read that the 164 does NOT like LED trailer
lights and either they wont work or give errors on the cluster. You
have to install resistors in the harness or something. This Uhaul
trailer had LED lights and it worked fine with no error messages.
