So should this work for 2021 Laramie with level 1 package, currently they call it level A as they have chip shortage apparently and only took $200 off package cost with out Blind Spot, level 1 is supposed to come with Blind spot, I ordered truck today but disappointed about blind spot detection feature not included. Would hope they installed correct mirrors and sensors in taillights anyway any one know if this is the case. Delivery 8-10 wks out now.

Is it possible to add Blind Spot?

Don't quote me on this but I would think it has to do with the position/projection of the sonar pulse.

They are the same part number. An extra ground wire for the passenger side sensor is how the system determines sides.
I'm looking for both, the sensor and the metal cover ,for driver side

Can someone tell me if the BSM taillight jumper harnesses have changed after 2019? I have a 2020 1500 DT and it comes up as not compatible and offers up a diiferent part # of 68505930AA and 68505931AA as a possible replacement, but I believe these are for a truck with ram boxes.
Thanks
I think I have it sorted out. I took a look at what I have installed and it is the same harness on both driver and passenger. Part # 68441333AA. Both harnesses have all 12 slots in the connector populated with wires already. I think I just need to pinin the BSM connector in the taillamp socket and the inside can bus wires and I should be good to go
Can you let us know how it went? Did you add the bsm monitors to your existing tail lights and then wire them in?
I have a 21 Big Horn Lvl 1 and have a set of the led tails with the bsm already installed. Would I just need to add the wiring under the driver seat?
Any help or input would be appreciated.

Successful install! Thanks to all that provided input for this mod. Also thanks to @Roman2179 for the parts and @Jimmy07 for the harnesses. I modified the non BSM LED taillight housing. No blind spot indicator on the mirrors but plan on just adding a small amber LED in the door panel or trim. That will be good enough for me and is much cheaper. Thanks again for those that share the knowledge!

Pinned the LED to C1 connector (the "B" location on door module) to pin7 (+) and had to tap existing wire in pin5 (-) ground. Works good.

did you drop voltage with resistor? not too bright ?
Great question, short answer is "no". But, I haven't tested at night yet. Initial day time driving it seems just bright enough for both daytime and night time driving.
Edit: Here is a daytime look with the indicator LED enabled "on" via AlfaOBD.

I believe @Roman2179 is the one that might be of help with this.

Yes. It’s the same process. You need the tail light jumper harnesses (or at least check your existing ones to see if they are already the right ones), and the missing section of canbus wires going to the can IHS block- except the HDs, the wires don’t go from the connector under the seat, but from the one behind the front driver side wheel well. If you have tow mirrors, you can just swap the glass out for the glass that has the indicators. You can’t use 2019 tail lights BSM part numbers on you 2020 HD, you must use 2020+ sensors, or 2020+ tail lights with sensors. I can build you the harnesses for the mirror glass, and the canbus harness if you need.

Thanks, Jimmy. Do you happen to know what the part number for the 2020+ BSMs is? Hoping it is not this one 68442393ae
. I had already bought two of these 68263397ad but it is sounds like those are the ones you are saying don’t work, ugh. Interested in the harnesses for the mirror glass and the canbus. If you can pm me with pricing info that would be great! Thanks. Sent from my iPhone using Tapatalk Pro
I hear ya man. I order my Laramie with level 2 right at the time when they changed the name to "B". I didn't know they removed BSM until I took delivery. I was pretty disappointed. So I'm following this thread closely.
I'm curious if my tail lights have the sensors but I assume not because I think that is the part with the chip shortage. My tow mirrors do not have the indicator btw.

Like nanDakota, I just took delivery of a 2021 Ram 2500. I ordered the truck with Laramie Equipment Level 1, the Safety Group and the Towing Technology Group. The Blind Spot Monitoring with Cross Path Detection was part of each of these packages. The truck that was delivered had Laramie Equipment Group B, Safety Group B and Towing Technology Group B and non of these groups included Blind Spot Monitoring with Cross Path Detection (BSM). I use my truck to pull an Airstream an average of 12,000 miles a year and drivers on the road are becoming far more aggressive which is why I wanted BSM. I am very interested in adding BSM to my 2500.
I have looked at my tail lights and the wiring to the plug is not fully populated and there is no BSM module in the tail light assembly. I am assuming that I will need both tail light assemblies, 2 jumper cables for the tail light assemblies and hopefully, one of Jimmy07’s CAN bus harnesses. If anyone has the part numbers for the tail light assemblies with the BSM module and the part number for the tail light jumpers, it would be greatly appreciated.

Thank you guys for a detailed story on how DIY this mod. I ask you a couple more questions,
- if I replace only the mirror glass without changing the case, can I connect the blind spot indicator with a some custom cable, and where exactly?
- Replacing halogen taillights with led is plug-and-play, just add them after by AlphaOBD?
