Missing Blind Spot Monitoring

From what I have read, the BSM is disabled in your truck when you connect a trailer, regardless of what kind. Starting in '20, they changed it to work with conventional trailers, but still disabled with 5th wheel. Seems like you can swap in tail light assemblies from a '20 and get it to work with a trailer, if you wanted, but I'm not positive about that.

I could never rely on any sensor, ignore all and do things old fashioned. I was just curious about the lil’ triangles, figured it was something like this deal.

does anyone know if there is a youtube video of this being done...going to add this to my 22 but im more of a visual learner lol

I believe some documented it with pictures..you just have to find it in one of these threads

I'm looking at adding the missing wires to the taillight jumper, rather than purchasing new ones. From the forum, I have the pin location that need to be added on the taillight side, but I haven't seen any info on what location the pins need to be added to the body side. Does anyone know if the jumper is wired 1 to 1 (i.e. pin 1 on the taillight side goes to pin 1 on the body side, and so on)?
Alternately, does anyone know the connector designation for either side of the body connector so I can look it up on

Why not just buy these? I think they are like $40-50 each roughly

I’m in the middle of this install. Got harness in that Jimmy made with pins 5,6,46,47 now stupid question but do they plug into the green/black block or the green/white block? In this thread I didn’t see that noted and I can’t figure which one because they fit in both. Thank you

Green/white.
The other end should be 5,6,46,47, not 4,6…

Well, I have three reasons.

1. I'm cheap
2. I wouldn't end up being able to throw away the old harnesses, so I would end up with more stuff in my garage
3. I have a lot of experience in designing and building wiring harnesses


I updated the harness with the following wiring, and it worked fine
Tail light pin is the first number, the body side pin is the last number
Taillight Body
1 * REAR PARK LAMP WH/OG 4
2 * STOP LAMP WH/GN 2
3 * TURN LAMP WH/YE 8
4 * BACKUP LAMP WH/VT 7
5 * GROUND BK 10
6 NO CONTACT 5
7 * LIGHTING FAULT SENSE WH/BG 11
8 GND/NO CONTACT (select) (Black) 12
9 RUN RELAY CONTROL PK/YE (Yellow) 1
10 CAN IHS (+) DG/WH (Blue) 3
11 CAN IHS (-) WH (White) 9
12 GROUND BK 10

* in existing harness

I used:
Pin for tail light side Molex 33012-2003
Pin for the body side TE connectivity 7-1452668-1
Seal for body side TE Connectivity 964972-1

Since the tail light side needs two ground pins, and the body only has one ground, I needed to splice into the existing black wire going to tail light pin 5, and run a wire from the splice to pin 12 on the tail light side.

Sigh…. New to me 2022 Laramie Mega cab owner here. I just figured out I’m in the B safety group pickle. Another project in my future I’m guessing. Thanks for all the wisdom shared here.

How did you wire the inside of the tail light that goes into the BSM? Are both sides wired the same?

It's easier and safer to just get the harness, a few minutes and you are done, no chance of mispinning anything.

 

[duenasl]

I already have the harness. I need to know how the bms sensor was wired inside the tail light.

Sorry to revive an old thread but i ordered all necessary parts to do this upgrade and was wondering in Jscan what i need to enable for the led tail lights to work. I currently have bulbs.
