2018 XLT Sport
 

Hello All,

I am new here (First Post) I have a question that has been asked a few times but not about the 2018 F150's. I tried to add a tailgate light bar to my truck but when I try to plug it in the truck detects a trailer. my question is if I clip into the wiring harness behind the plug will the truck still detect a trailer? and if so does anyone have a suggestion on how I can get around this??

Thanks
Mike

What tailgate bar do you have? So far as I know of only the Putco wiring option works to not have the "trailer connected" message. I have the putco bar installed and it works perfect. You can google or search here for the 2018 wiring diagram but I think you would need a specific one for your manufacture of the LED light bar.

I believe you need to connect it to the tail lights, instead of the trailer wiring harness. If you connect it to the trailer harness, it thinks you connected a trailer, where if you connect it to the tail lights it doesn't know any difference. They're separate circuits now where they used to be the same wires in older vehicles.

Thank you guys.... now that the weekend is here... I will try what you suggested.... I have some no name light bar roll I got off amazon
