I am installing a F150LED tail light bar on a 2024 F150 XLT that has the Blis system in the taillights. Been trying to find a color code for the wiring, I have found out that the large connector fir the Blis system is where the reverse light wire is located and the smaller connector is where your turn, stop, and park lighting wires are located. Does anyone know what color code the wires are for those? Been searching with no luck. Figured at worst I will go to a Ford dealer and see what they say, might be the quickest way to solve my issue.
The included directions don't even come close to the wire colors in the assembly.
Thanks for any input to this issue......

 

I found the simplest way was to get a test light probe when I installed a light bar on my 2021. Half the time I can't read the diagram correctly and the other half of the time the colors don't match...so the test light solves the issue. Grab a friend or kid to help press the brake, turn signal etc etc.

I also highly recommend you take the tailgate off. It makes the install way easier, and you're more likely to get a nice straight line without it sagging on the ends. But if you do remove the tailgate don't forget to unplug the backup camera first. Don't ask me how I know.
