The dedicated connection for an F-150 C1R
DD4150 · Harness only · 2021–2023 Ford F-150
Connect a compatible C1R HitchMount lamp to the truck’s trailer and tail-light signals. DD4150 is the vehicle-specific harness package used in the complete DD7649 kit.
No LED pod is included. If you need the lamp as well as the wiring, choose the complete C1R kit.
Match the lamp and factory equipment
- For the supported F-150 C1R installation, not a generic C1 Sport harness.
- Check the vehicle’s factory tail-light functions against the supplied signal-harness selection table.
- The inline connection fits behind the factory 7-pin trailer socket, with a DT connection to the lamp.
- Operating input is 9–16V DC.
The complete installation routes a signal harness between the tail lights. Connector shape alone is not a substitute for the exact harness, signal and vehicle match.
Follow the F-150 connection sequence
The BTS guide contains all eighteen original technical images, including the adapter-selection chart and driver/passenger routing.
One wiring-harness package
This listing supplies one DD4150 harness package. It does not supply the C1R pod, HitchMount sleeve or optional locking pin. SafetyStrobe selection is covered in the harness guide.
