As many of us know, the 2017 FiST did not come with the glovebox ambient lighting strip or glovebox lights included in previous model years. You can purchase the OEM Ford harness with these missing LEDs, but splicing them into the existing ambient lighting system isn’t easy if you want to retain the option to return to stock in the future.
For this reason, I built a few Y-splitters for the factory wiring that provide a completely reversible method for adding the LEDs to the existing lighting system. The splitters use connectors matching the Ford factory connectors so they plug directly into the factory wiring, thus making it easy to convert back to stock if needed. Thanks to others on these forums for listing all the part numbers associated with this!
I built a total of 4 splitters (one for me), so I have 3 that I am selling. PM me if you want one.
