HOW TO: Add Digital Rearview Mirror

[mlcjohnson16]

Here is what I have so far:
I'm working on is adding the Digital Rear View Mirror with 2 inputs and Forward Collision Warning / Adaptive Cruise Control to the Ram 1500 (my current regular mirror has both of those.

I also added the Backup Camera Kit (Which I think is the camera kit for on the trailer itself, but maybe it is the wiring for under the truck. Getting necessary components to go from the DRVM to the bumper of the truck is where I'm stuck. I added a trailer tow connector and a dual camera housing in this parts list, but wonder if I'm missing something.

Do you know if the backup camera kit below is all the wiring for on the trailer or the underside of the truck. If it is for the trailer, do I simply need another longer FAKRA cable to snake through (or possible multiple) to get from the DRVM to the Bumper where I'll install the tow port?

My Ram VIN is 1C6SRFJM7NN353467
The parts I have in my cart are (hyperlinks included):

Inside Rear View Mirror: 68519222AA
Center high Mounted Stop Lamp: 68551077AB
Back Up Camera Kit: 68527599AA
Trailer Tow Connector: 68532403AA
Trailer Tow Connector: 68532402AA

In the process of installing the mirror, 2022 RAM 2500, CHMSL and cable already fitted some time ago.
In the process of checking that the mirror covers from the original mirror will fit, found major differences.
Are there specific covers we need to use on a 2500 when fitting the DRVM?

Hey all. I wired up the mirror and brake light cam today and have the 24 foot R58 fakra female cable coiled up in the back bumper. Does anyone know what kind of plug the trailer camera kit uses to plug in? It looks like a kind of typical coax connector but I don't have space on the bumper where I can install it so I'm trying to just buy an adapter to fabricate something smaller but don't know what kind of connection it is.

Hello, I really was trying not to post a question on this but after 4+ hours of reading forums and sorting through part numbers I'm still confused.

I have a 2024 2500, and am very much regretting not buying the DRVM. My primary use is to have use of the rear view mirror while towing and with having a bed cap on. It seems like I have two options for adding it on after the fact.

Option 1: Buy a 2022 DRVM, buy two cameras that would normally mount in a CHMSL (one to mount on the bed cap and the other on the trailer), buy the appropriate length cables/adapters to get the camera's plugged into the mirror. Pro is that this is relatively straight forward and likely the most cost effective, just takes a bit of time and cable routing. Con is I don't get the DRVM 3.0 function and you have to deal with the error message that pops up when you start the truck.

Option 2: Purchase the 24 stock DRVM, purchase the extra camera control module that goes under the driver seat, purchase the trailer tow connector + trailer camera kit, somehow get everything hooked up and it's basically like it came from the factory that way once the appropriate settings are enabled. This would also require a purchase of the camera for the bed cap and a cable to get to that camera control module, but that seems pretty straight forward compared to everything else.

So the question is, have I summed that up properly and is option 2 even viable? I've gotten the most conflicting information on Option 2 especially with that camera control module. I would default to option 1, but I'm a little worried about the length of cable required to get from the trailer to the mirror for everything to work properly.

I believe you are referring to the female side of the connector that would normally be on the truck which sounds like it is entirely proprietary. I believe this post/page is relevant which I came across earlier: Adding camera to Digital Rearview Mirror . Jimmy07 talks about it half way down.

Hello, i did the chmsl and mirror upgrade but im having issues with mirror.

I did make the 2 changes in alfa. I have a 19 truck with 2023 BCM

Here is a list of parts i have:
68448640aa chmsl camera
68448641ab mirror

Im having no display show up on the mirror regardless of where the tab is flipped….

Even if have camera cable unplugged i don’t get any error messages and the mirror just stays blank. Not sure what im missing.

Just to eliminate the cable issue i took a 1ft female to female fakra cable i had laying around and removed the camera from chmsl housing and plugged it into mirror but still same. TIA

[mention]Jimmy07 [/mention] [mention]vincentw56 [/mention]

Any ideas on what could be wrong?

UPDATE: My old mirror has the auto high beam camera so i went into auto high beam and module location settings im Alpha and set them to NO as well but that still didn’t fix the issue….

Did you upgrade your BCM to 2023 or is it only added with the Jimmy harness?

 

[Abhi.K]

I have 2023 BCM installed in truck by dealer when i did aux switches. I have the MY set to 23 as well for Uconnect 5

 

[Cesar592]

In your BCM you see some code

I only get U1514 but thats been there for a while since i replaced SGW with Tazer DT

I don't know how it is on the 2019 but when I did it for my 2022, I plugged my falkra cables (the blue head cable) directly into the digital rear view mirror not that weird outlet you have it at

This is the connector i am using coming directly from the mirror. Did you have something different?

 

[MannyN]

What are the 2 other plugs dangling down by the mirror? I have the same setup on my 2019 with a 2023 BCM. No issues, what so ever.

That is for the ACC DASM upgrade and the other wire is for my radar detector. The DASM wiring isn’t connected to anything yet. I just ran it to headliner and the radar detector wire just taps into mirror connector for power.

I stand corrected... literally did this 6 months ago and forgot already. But did your truck originally come equipped with FCW/ACC? Probably have the wrong part, also double check your connection to the brake light mine got loose putting it back in.

 

[Abhi.K]

I stand corrected literally did this 6 months ago... and forgot.. im getting old. But you got the DRVM directly from MOPAR right?

It came from a used vehicle but the seller is reputable and i bought stuff from them before. Im starting to think its either the camera or mirror module but i think mirror is fine because it at least displays something and i don’t have any way to test camera or know if its working unless i get a replacement. I guess i will have to try replacement camera since its cheaper..

Truck doesn’t have ACC yet but im working on it and thats why decided to do this upgrade while i was at it. I don’t think ACC matters for the mirror since it runs on LIN bus and people got this mirror on other posts and were able to add it without ACC but had issues with plastic housing not fitting

 

[MannyN]

I think the mirror is fine, it shows the symbol to switch to regular but it also shows camera not connected. You have the right digital camera. It is either the camera or the Farka cable.

Yeah im suspecting camera as well. The part number is right (i checked camera housing 68448640aa) and i did eliminate the fakra cable by removing the camera from CMHSL and plugging it into mirror with a different 1ft fakra cable just to make sure its not a signal loss by long cable but still had same issue. Theres no lights or anything on the camera module to tell if its working or not so i will just get another one and update if it fixes it hopefully…
