When installing these kits on trucks that have OEM headlight housings, you will not have an individual bulb for your side marker lights. There is a single connector to your headlight assembly that we need to connect to.
For 2017-20 Super Duty Models, we recommend using PIN7 for ground and PIN6 for power.
6 - Parking lights
7 - Ground
For 2021+ SuperDuty models, we recommend using PIN7 for ground and PIN8 for power but you can also utilize the DRL for power (PIN4).
Below is a 2021+ reference photo.
