Howdy!
Would anyone have, or be able to confirm, the direct-connect wiring of an LED light bar into the truck's 4-pin trailer wiring harness?
I believe the LED's reverse red wire needs to connect into the driver's rear taillight reverse red wire (shown below). Thanks in advance.

Should be possible as long as you're not pushing like a 30" light bar. That's the same way the Diode Dynamics hitch light works.
 
I’m sorry if I’m not being clear with my question.
I don’t want to use the 4-pin plug that comes with the LED light bar and I need to know how to direct wire to the 4pin, or even 7–pin, wire harness that is factory-installed on the truck.

My diagram above is blank on the right side because that’s what I need to know about the wiring harness.

Thanks again. 😄

I installed the OPT7 Redline Parlux Triple Row LED Tailgate Light Bar and used the OPT7 Easy Connect USCAR 7 Pin to 4 Pin Harness, 4ft Trailer Extension Wiring Connector Adapter for Trucks, Pickups, Trailers, Compatible with Redline LED Tailgate Light Bar, Trailer Lights from Amazon. This adapter sells for under $30. Very simple install.
