Anyone install 2024 OEM LED bed lights

[this1aintinuse]

So, after seeing issues with finding the proper harness, I decided upon a modified factory route. I bought the cheapest harness that I could find that supports bed light.

(ebay donor harness)

I received the harness, cut it apart and separated the bed lights portion out. I separated the main connector and extracted pins #28 (GN-OG) and #31 (WH-BU). The grounds are all ganged together so I cut the grounds that went off to the tail lights and sealed the cut ends with heat shrink. I split loom, vinyl tape and wrapped with cloth tape to make my own harness that piggy backs along the existing harness.

(pins for 28 and 31 location, if you notice the one is white with green trace instead of blue trace bc I botched the extraction and soldered and heat shrinked the next closest wire color I had in the donor harness)

You should be left with two pins, a ground lug and two connectors that go to the bed lighting jumper harnesses. The ground seemed to want to go on the right frame rail, but I soldered in more wire so that it would bolt in with the existing bundle of grounds on the rear of the left frame rail.

(custom harness just for bed lighting)

I separated the main connector on the truck, pulled the plastic filler plugs and inserted the to pins from the new harness I made into locations 28 and 31. I was able to extract and insert these pins with a micro flat blade screwdriver.

I ran the new harness along the existing harness and cable tied them together. Installed bed lighting jumper harnesses and bed light. Hooked up and activated in forscan, now I have factory bed lights with a donor harness that cost me 40 plus tax and ship.

I taped the harness too close to the end of the bare pins and had difficulty installing the pins in the connector, I had to cut back the tape a couple inches and pull the wires out of the split loom to ease inserting into connector. The wires do have room to go back into the loom once the connector shell is snapped back together.

I now plan on installing factory upfitter switches using my own harness made with connectors found from digikey and mouser.

I am impressed with your knowledge and fortitude of installing your bed lights without paying $200 for a factory harness.
For the rest of us mere mortals, this is the harness you need for a XLT 24 and 25 (without PB):

also, XLT 24 and 25 PB 2.4kw:
RL3Z-13A409-F

not sure what harness is required for the XLT 24 and 25 PB 7.2kw? If someone wants to get a gold sticker by their name- feel free to put together a spreadsheet of harnesses and models/trims/options that can be saved.

I have done almost the same thing except I made my own complete harness. I finally bought a pin kit that hopefully has the correct pins in it.

I’m very interested — could someone show how this looks attached to the harness, especially where the pins are connected? Also, to insert the pins into the original harness, did you have to unlock or release the harness to access the pin holes? Thanks!

I will get you some pictures today as I am adding the pins to my harness. With my experience in repining a connector you typically need to remove an inner piece of the connector to so the new pins will slide all of the way in and lock into place. I will have to take my connector apart to be sure I am using the correct pins from the kit that I bought. It is all pretty easy once you get over the fear of messing up your truck lol.

Appreciate it!

To add new pins I just pulled the white/clear center piece out it pops out pretty easy. Once you do that you can insert your new pins very easily. I pulled the plug wire in the photos just to show what the correct pins look like.

Nobody still has any idea if on the truck side of the C408 plug you do not have wires in Pin 28 and 31 where they come from? To reiterate, I have the new taillight harness but no wires from the (BCM???) to provide power.

I am searching to see if I can find the answer to your question. What package do you have?

I might be getting closer to an answer for you. I found this thread on a different forum for a 2018 300a. I joined to forum so I could ask about your truck

Its a 201A build (michigan plant)and thank you for looking into this.

I just ordered connectors to make marker light splice connectors (I already have the pins for the connectors) but I also ordered the male pins that I believe can be added to your bumper harness in spot 28 & 31. I will post a link to the pins if they are correct. I could actually post links to everything to build your own complete harness. This place is way cheaper than Amazon.

Yeah, DigiKey is awesome. I ordered my pins and plugs from them for my ambient set up.

The tailight harness i got from ebay was 100 bux and OEM. It has the pigtails and all the proper wire.

My truck does not have the appropriate wires from the BCM or where ever.

I think I am getting closer to figuring out your wiring to the BCM. See if this helps you any

I know this is for a slightly older truck but See if this thread helps you any.
