TRUE MODS Tailgate Light Bar Signal Relay Box [4-Pin Flat] [Ford F-150 F-250 F-350 Super-Duty up to 2018] [Tow Package] [BLIS] Trouble-Shoot Solution for Ford Pick-up Trucks with Error Code

installed a light bar on my 2020 f150. the blinkers would not work on the light bar. . so installed the led box. and now the blinkers work good now. it fixed my problem.

The item itself works great and as intended but if you have a 2014-2023 Ford F-150, don't bother buying this for the cameras and safeties built into the epim. It doesn't bypass them. But I'd imagine itll work for other vehicles.

2016 F150 Platinum with the LED taillights and BLIS system. Using an OPT7 tailgate light bar. Tried plugging directly into the trailer connection and the vehicle still comes up with the message that a trailer is connected. I then wired in between the OPT7 quick connect harness ands the light bar. It worked! But only for about a month before the left signal stopped going through. Put in for an exchange and the seller cancelled it (that's my guess because it was just removed form the orders list) Now I'm just trying to return it for my money back.

Didn't work. BSM and trailer hookups still showed as connected?

Simply put, it doesn’t work. My 2015 F150 still showing “trailer connected” when installed. Unable to reach customer service because their phone services have been suspended!!
