Under Tailgate DOT light ??

I got my light in the mail the other day.
I purchased the two push nuts
installed the light - there was a plug right behind the plate. I thought, SWEET!! It's for the light!! I have to do nothing but plug it in! But it wasn't the right plug. Not sure what it was for, but I thought I was lucky.

I have the "T" harness coming so I can wire it, was supposed to be here today, but it's been delayed due to 'weather' - so I'll tackle the wiring tomorrow. Probably easier to drop the tire, sit upright under the truck, and wire it! :)
 
Here are those plugs I was talking about. I don't have the parking sensors. Figured one of those would be for that. But I thought man! I just have to plug in this light and I am done. No, I wired them into the T harness I purchased so I didn't mess with the factory wires.
3rd picture, with the female plug is the plug for the DOT light. Doesn't match up. All those other plugs had 3 wires and the plug didn't match. Wonder what they are for?

It's real easy with this kit....plug and play...did it on mine.....
 
As long as the rear facing lights are red you are legal .

Holy guacamole'

I guess if you have to buy all the parts, connectors, etc. for a one and done and never do other wiring, it's a reasonable plug-n-play.

I do now recall I also added a 2-wire Aptiv connector when I wired mine up. Already had the kit.

Thats quite an inflated cost!
 
You should look a bit further up the frame rails for the connector. Maybe the factory/upfitter wiring schematic will so you the way. That light is designed for the dually so, with that, the harness also includes the leads/pigtail connectors for the 4 individual marker lights for the fender clearance lights. Two each side. Amber forward leading edge of the fender and red for the trailing edge of the fender. So you'll have 5 leads coming off the main connector wire bundle. Maybe a trip to your local Pick-a-Part and scope out a dually .
