Tailgate LED light strip

STX30MAC · October 5, 2020

Does anyone know a way to wire the Tailgate LED light strip so it does not flash every 15 seconds when the truck is off. I would also like for it to not turn off my back up sensors.

I have tried plugging into the 4 pin trailer connector and splicing trailer wires. Still have flashing and sensors shut off. Also shows I am always towing a trailer.

Tie into taillights. Putco makes a plug and play harness. If you plug into trailer harness then truck will think you have trailer attached.

As stated above, you need to get signal directly from the tail lights. The Putco harness does this. The new truck runs all the trailer light connections through the BCM so you can't just plug into the 4 pin or 7 pin output anymore.

Got the Putco wiring harness. LED strip works like it should without turning off sensors and blinking while parked. Thanks for the info.
