I did not do a write up on how I installed and wired my bed lights as it seemed common knowledge at the time, however I have been receiving multiple requests in recent weeks for how exactly I got the job done. So I figured I would offer a write up for anyone interested.

These steps were performed on a 2012 1500 and they should work on other 4th Gen Rams. Please check the color of your truck's wires and the wiring layout to confirm.

Following these steps, your bed lights will be tied to the cargo lights (located in the 3rd brake light assembly). They will illuminate when you unlock the truck and then fade out with the cargo light after about 1 minute. If the lights are required for a longer period of time, simply hit the unlock button again and they will illuminate again. Alternately, you can control the bed lights with the cargo light button located on the dash near the headlight controls for a constant on.

I bought this kit from eBay.
Installed the strips to either side of the bed (wire ends toward the cab) using the 3M tape the strips come with on them.
My Ram has a spray in bed liner and I have had no issues with the 3M tape holding fast to the liner on the underside of the rails.

Fed the wire ends through the driver side hole on the stake post in the bed (it is a pass though about 2/3 up from the bottom of the bed that passes through into the space between the bed and the cab).

Snaked the wires down under the cab and up through the access hole located under the driver side rear passenger seat. (Flip up your driver side rear passenger seat, then open the storage compartment. Under that carpet liner is the access hole I am referring to. You can see it also by looking under the truck.)

Popped the cover off the driver side rear passenger door sill to access the wiring harness. I tapped into the dome lights wire (white w/tan stripe) and grounded the black/ground wire to a nearby frame screw.

Finished product:

Looks great! I am a little confused with how you go from under the passenger seat storage area to the passenger door sill?

Thanks.

Are they blue or white? They look kind of blue from your photos. Can't tell but I would think bluish lights would not light up the bed as well as white ones would.
Anyways, nice write up!

Wouldn't that screw your warrenty.
I know any dealer i talk to ,says you're fubar'd on wiring warrenty as soon as you tap into the factory harness.
Also seems mighty complicated,a simple switch at the back that goes to the battery,seems like a better way,and doesn't screw up your wiring warrenty.

I did mine the same way but tapped into the cargo light circuit by adding a relay. Jim there is a gap at the bottom of the storage compartment that goes right into the door sill wire channel. Kai, those bed lights look awesome, :smileup: I'm going to be replacing mine with white ones very soon as the blue ones I used are just not bright enough.

Randy (RamsRAM) nailed it. There is a small gap - just pass your wires through there to get them to the door sill.

They are white, but with a very slight blue-ish tint in pictures. In person, they are a clear, bright white.

I t-tap into the factory wiring.. absolutely NO splicing here. My dealer is always impressed with what I have done each time I take her in for whatnot and I show them exactly what I did as they are always wanting to copy it and replicate it on their personal trucks. So, there are no issues with my warranty being void on any level.

Bed lighting can be installed various ways. There are a number of write-ups on here explaining different methods others have chosen to do, including installing a switch near the tailgate or a pressure switch that the tailgate activates. Personally, I preferred to go as simple as possible with my install and just tied them directly into the cargo lights. I didn't need an additional switch.. however all methods work. Just have to find the one that works best for you and your style.

Thanks Randy. I hear you on needing lights to be bright. This kit is certainly bright enough to illuminate the entire bed (I just didn't remove my emergency tub for the pictures).

Hey there. So I followed your post here and bought the kit you listed and installed it today, but they're not really working. Only like 6 lights on one of the strips actually turned on when I tried. Not sure if I got a faulty set or if I did something else wrong. The kit I got came with 4 shorter individual strips which i wired together. Tapped the white/beige wire and turned it on, but only got a few lights and they didn't even seem that bad. I'm thinking I did something wrong because I can't imagine that all 4 of the strips were bad. They also didn't stick to my spray in bed liner. They kept falling down. I can fix that as long as I can get the lights to work. Just wondering if you have any suggestions or things to check. Thanks.

I wired up a set of bed lights a couple of weekends ago…. Fortunately, the 2500 Laramie has five Auxiliary Switches, for aftermarket use, and I made one of them my bed light switch. Just had to tap my positive wire into the correct spot under the hood…..

This is how I wired mine. Compare this to what you did and see if you can't pinpoint the issue. The eBay seller we purchased from is very good at working with you. LEDs, like everything else, can be defective some times and you can get a bad batch. If your problem isn't fixed after checking the wiring, then contact the seller and see what ideas he has as he did wire them himself. Hope this helps!

KA1OTE,

Nice write up! I'm going to be purchasing the same very soon thanks to you. How emergency tub you say!? That's a tread someone should start... Who carries a "get home" or "bailout Kit" in their trucks.

I have one but it's still in progress.

like this idea a lot. gonna order a set myself, can't wait! I am a little concerned about the warranty problem potential but i guess if you had an electrical problem you could undo your tap in and they couldn't say anything----

My dealer and svc manager have seen everything electrical I've done and say there's no issues or concern about voiding my warranty. If an aftermarket mod is installed correctly (basically, without stripping the factory wiring and doing bare splices), then you should be good to go. :smileup:

Kai, the guy on E-bay owes you some commission :LOL: I ordered a set last night and I got a e-mail today that it had already shipped. I know of two others that said they had or were ordering.:smiley_thumbs_up:

Rrriiiiight! LOL! Nah, I'm good. I'm just glad he is getting the business he deserves. He is a superb seller - quality items offered with fast shipping. And he backs up his product. So, as wonderful as a monthly check may sound, just happy you all find him (and his product) as useful as I did. :smileup: ;)
