So the XL trucks and trucks not equipped with fogs are equipped with the plug for them? That's handy.

Wiring diagram for plug on chassis?
I’m trying to figure out what all 8 wires are on my 2021 super duty, I know 4 on the harness from my bumper are for the lights but what are the other 4? Trying to see if I can utilize any of them for some marker lights I installed on my valance I want on when my running lights are on

Four of the additional wires on my 2021 were for adaptive cruise radar sensor. 2 CAN wires and the other 2 for power and ground.
