Current preference — no decision made
Why this option
Extends the factory upfitter switch wiring so accessory lighting can be run off the OEM switches rather than spliced into a separate aftermarket controller. 6-wire version for 2021–2023 F-150. Keeping accessories on factory circuits is the same principle driving the rest of the build: use what Ford already engineered before adding a parallel system.
