The wiring system of the 2016 Ford F-150 has a combined tail light wiring system. The turn signals and brake lights are on the same circuit. Since the light bar is wired to the combined lighting system the turn signals illuminate when you press the brake and vice versa.

I recommend separating the combined wiring system using Pacer Performance 3rd Brake Light Logic Module part # PP20-702. The two yellow wires wire to the right turn and left turn signals from the tail lights and the green wire connects to 12v power wire coming from the light bar. I have attached a wiring diagram for your reference.

Answer 5

The part #PP20-702 has to connect to both the left and right hand turn signal/stoplight circuits in order to separate out the stoplight. The reason that is because it waits to see voltage on both circuits at same time to then allow the stoplight…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…
