Trailer Wiring Question

[Amiodynski]

So, on my 2015.5, I installed a Tailgate Light that simply plugs into the 4 pin socket on the Factory wiring plug right below the 7 pin.

 

I would like to splice that connection on the back behind the bumper so A: you don't see it plugged in, and B: so it does not block the 7 pin plug.

 

I poked around under the rear bumper Sunday, and was able to un-clip the factory plugs from the bumper, but there is not enough slack in the wires to pull it out. Anyone know which is the best way to accomplish what I am looking to do.

 

I tried to "google" it, but had no luck.

 

 

Thanks in Advance !!

Here is what it currently looks like

I have the same style light bar, and what I did (or rather, had someone do) was get under the truck and hardwire the bar to the 4 pin's wiring. Now I can just plug in a trailer if needed, and it will work.

 

 

EDIT: I'll try to get under my truck later and snap a picture for you.

I would great appreciate it. I'm not afraid to do it on my own, but I don't want to have to guess on the wire colors.

There is only one harness for both the 4 and 7 pin connectors. It's the one with the gray head. I couldn't undo the taping that was done, but I'm 99% certain that the tails are the brown wire, which is where to wire the bar.

 

If your bar goes white on reverse like mine, the separate white wire that it has should splice into the purple wire, or to your left reverse light wiring.

 

I'm sure someone can confirm this for you on here.

 

Cheers!

If you haven't already tapped into the wiring, you could save yourself some time and add another flat-4 style connector with an adapter like this one - http://www.amazon.com/Curt-Manufacturing-55384-CURT-T-Connector/dp/B0009FJ38Q

 

I have the Recon "Xtreme" Amber Scanning Tailgate Light Bar on my Silverado SS. I tapped into the tow harness on it. I feel I am more than adequate with a soldering iron and wiring, but after about 3 years the liquid electrical tape, tape, and wire loom gave up and let some water in, shorting out the bar. I plan to add the same model light bar to my new 2500HD High Country. Since that light bar needs a 12v+ and a reverse light, I plan to use the bellow 7way t adapter for the wiring and cut off the female side so that I have a clean tap ad the factory harness - http://www.amazon.com/CURT-Wheel-Goose-Extension-56070-7FT/dp/B0031GHBSE/ref=sr_1_1?ie=UTF8&qid=1444936856&sr=8-1&keywords=curt+56070

I appreciate you steering me in this direction! It looks like all I need is the first t connection since my bar is installed already and I ran I wire to my tail lamp for the reverse wire already. I'm guessing all I have to do is unplug the back side of the factory harness, plug this in between it and the connector, and use the 4 pin for the bar, right?

Yes, So long as that's the right t connector for your setup. You can confirm on the Curt website, but it should be right. I have a 2015 2500HD High Country and this is the right one for mine. Just plugs inline with the factory harness and gives you another flat4 style plug behind the bumper.

If you have the 5th wheel pigtail for in bed plug that's what I wired to.

 

I have four Recon light bars on the truck. 2 ember on the sides under doors. 2 on back under and on top tailgate. Problem I had with Recon is fuse holder. Small spring wears/rusts out and no longer makes contact. I cut the fuse holders off and go with a blade style holder.

I know the truck has the wiring for a 5th wheel, now I just have to find it.

Should be between the license plate mount and the spare tire. It will be zip-tied to the tow harness if you have fifth wheel prep (that's an option separate from the tow package.) If you don't have that option, you can get something like this so you're not hacking into the factory wiring - always preferred.

Exactly. I ordered Curt part number 55384 which is probably the same for you. Should plug right in line with the factory tow harness behind the license plate.

In case it helps, the Curt Part was exactly what I needed.

 

Pop out the trailer wiring assembly squeezing the 2 retention clips behind the bumper.

 

 

The product plugged right in no problem.

 

 

I needed the 12v+ and reverse for the recon light bar so I soldered 2 new wires to the harness adapter and then added a weather tight 2 prong connector next to the 4 flat trailer connector.

 

 

 

Haven't had a chance to put the light bar on yet with the adapter, but have tested it. Works great.

Awesome, thanks! Ordering this today!
