On a '14, there are prepunched holes under the bed rail that small clips snap into, and the mounting screws screw into them. As long as the bed liner material hasn't filled them in, you will be OK.

 

Thank you! Getting the liner tomorrow so I'll make sure they don't fill them in

I installed the after market ones. I tied them into my cargo lights. Great mod!!     Sent from my Galaxy Nexus using Tapatalk

Just as a heads up: The junction box comes with a cover for the plug that these plug into. So I made my own plug out of the cover with a couple parts from other plugs i had laying around and sealed

How are y'all wiring them into the harness if you buy a set that doesn't have the "plug" that the gm set has?

Ok, I have it; but can't find the switch.

 

If you have the factory ones it the same switch that activates the rear cargo 3rd brake light lamp. Located in the center console switch bank.

hmm incorporate that on the harness and have it to come on when opened :D

Make sure if you do this mod with the door jam switch that the switch is water proof. I did this on my 2013 and the switch lasted less than 2 months. Wasn't water proof.

I tied into the constant power at the trailer plug and run the wire up to the tail gate jam, drilled a hole and installed BedLEDZ and they looked great until the switch went bad. Also had to use a spacer as the switch was right at the point of on/off and wore my battery down over the weekend.

Also BedLEDZ did come loose, so there must be a better solution.

I want the lights up towards the front of the truck bed NOT at the rear.

I have not had any issues with the GM switch I used. There was no adjustment issues, or corrosion causing the switch to go bad. These switches were originally used in door jambs, and there was water in contact with them.

Has anyone tapped into the cargo light switch to turn the bed lights on?

I picked up a switch on ebay like this one. Didn't last long.

I picked up a second set of GM bed lights to install in my truck, it has factory installed bed lights but I want more!

I'll cut off the plug that goes to the module, and hardwire into my current bed lights. If someone is interested in the plug, PM me and I'll let it go for almost free plus shipping.

I have the 4 LED lights per side ordered from Amazon. I simply tapped into the brake light on each side. When I hit the unlock or lock the taillights come on and stay on for 60 secs. longer if I adjust the settings in My Link. This way there is no switch to worry about and risk of the lights draining the battery. Remove the 2 screws from the taillight and you gain quick access to he wiring. After 60 secs if I need the lights on longer I just hit the key fob again. Wiring the switch into the interior switch makes no sense since you have to go inside the truck to turn it on/off.

Not a bad idea. I am not sure if I will do this but it does give me another option.

I am wanting to install an aftermarket set of bed lights on my 14' due to the factory ones not being bright enough for my liking. However, I am wanting to be able to use the factory plug ( where it connects to the factory junction box under the bed ), Does anyone have any specs/pictures of how to do this?

 

For those that installed an aftermarket kit, on a 14' model, and spliced into the factory cargo light switch/wiring. How did you do so? I'm not interested in the pop switch types or the wiring into the brake lights deal.

For anyone who is looking to add some under rail lighting, or to be more specific, who already has the kit in their truck from factory and is looking to add a second kit. I just got my kit in today and noticed that the color of the LEDs on the second kit, which is a certified GM OEM part and should match exactly what is already in my truck, is slightly different. The colors are not exactly the same as shown here

Install was a breeze though. I decided to keep these lights to see how they look at night because they aren't as bad in person as in the picture, but are still noticeable. Just wanted to give a headsup to anyone thinking about doing this mod. sazadyga.jpg

 

Just feed wire through the side of bed until you can get it behind the taillight housing.

I decided to cut all wires and just recrimp them together so that it splits from one to two power/ground wires to go to each light.

From here I just crimped the appropriate wires together and then sealed with a nice tight electrical tape wrap. Checked that all were working properly and then reinstalled taillight. Then got on my phone and posted here haha.

Ok. I read through this thread and not sure if I am missing something. My truck has the factory led lights that are turned on/off with cargo light. I don't want to add more light. I'd simply like to add an addition switch to the existing lights in the bed. The new switch would go under the rail right near the tailgate. Is this possible? I am not overly concerned about water as I have a fairly water tight cover.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
