I added a third brake light to my F3-T. The biggest problem was what wire to connect to for the brake light to work properly. My F3 is equipped with the trailer hitch module. There are a whole group of wires that feed into the module. There are two RED wires that feed into the module.
One is a heavier gage then the other.
The thinner of the two red wires is the one you want to tap into for the brake light only.
Took me a long time to solve the problem of witch wire to connect to, since the F3-T uses combined LED brake/turn signals.
