MPGRIMM2,
I am not sure how to reply to direct comments. I wanted a cargo camera from the factory for my 2018 Ram but the dealers says "impossible". I just don't understand since you can order it from the factory on other models basically using the same hardware. If its a software issue, then why can't it be done at the dealer? Much to complicated for me to figure out so i purchased another tailgate backup camera with associated wiring. I mounted it on a suction cup cell phone holder. When i need to use it for putting my truck camper in the bed, I mount the camera on my back window, unplug the tailgate plug and plug in my "remote" camera. Now i am able to see my cargo area on my 8.4 screen just as if it was meant to be. I don't remember the cost but think is was a couple hundred dollars for everything. I do wish a software fix were available with the mounting of a factory cargo light/camera set up as on other models. It is what it is. I now have a 5th wheel and use it for that as well .... Just not the best method !!!!
What year is your truck?
I was poking around the BCM with the AE tool on my 2013 the other day looking for the CHMSL setting and must have missed it or it's not there on mine. (Thought it would be in Veh.Config 1).
Let us know of anything weird pops up after turning it on with the AE. @DeereGuy reported some oddities popping up on the 8.4 radio screen after doing it on his (ie power fold headrest button, and something else) that caused him to end up getting the BCM reflashed and CHMSL activated by the dealer instead.

Did you turn both of these to "yes"?View attachment 226974 View attachment 226975
I am trying to add an aftermarket Cargo Camera to my 2017 Dodge Ram 5500 tradesman. I can not get an image to appear in the CargoCam button. Backup camera works fine.
This is what I have done.
Purchased and installed an 8.4 Stereo Upgrade with custom harness by MPGRIMM2 through a 3rd party for AC controls.
Used alfa to turn on the CHMSL
Turned on the Led CHMSL (as I got a DTC right after first hooking up)
Backup Camera works fine via the button and in reverse.
I purchased a Jeep RCA wiring harness with a plug that I removed to already have the leads with the PINS on them.
According to what I have read I need to add the new wires to pins 24+ and 25- for the CHMSL Camera for 2016-2017 Trucks which is what I did.
Added 12v constant power to leads to test
No image will appear when cargo cam option pressed but it does display "Camera system Unavailable"
I have walked away overnight sometimes to allow the system to reset after making changes.
In the meantime I also:
Reversed the leads 24 and 25 just incase RCA was wired backwards
I also tried Pins 21 and 22 and 21 and 23 since those are also listed for 13-15 trucks
Current backup cam appears to be using 21/32/33
in alfa I an seeing DTC trouble codes:
U112 - Lost communication with Rear Cargo Camera
U0264- Lost communication with Camera Module
If I clear them they come back
I also hooked up a monitor directly to the RCA plug of the cargo camera and used existing 12v connection and verified camera was working and getting an image. I also tried to use a video out of a DVD player to attach to the RCA input to see if I could get an image that way. No luck.
I am assuming I either have it pinned incorrectly (I have tried and double checked many times) or something else needs to be enabled. But I am out of ideas.
Someone threw me a bone when I installed my remote start and told me I needed to drive my truck and then let it sit for a day and what do you know. That worked! And I had remote start.
I hope someone has a tip for me for this camera as well.
Did you turn both of these to "yes"?
VehConfig 1 - CHMSL Camera
"Yes"
CBC Features - LED CHMSL Lamp Present

Are you sure? I originally used the wrong pins too. Double and triple check.Thanks for the input. Yes that is the same pin location as I posted (front of plug vs. rear) I just needed to make sure. Out of ideas. The only thing I haven't checked is if the RCA cable is bad?
I got mine from Customtronix a long time ago shipped from overseas for around $80 but they've gone up in price. I would consider making your own using your current third brake light. I have a spare third I can send you if you want to go this route.Who currently makes the best aftermarket cargo cam for a DS body? I'm all set with my M2Mods radio harness and I'm just waiting for the shipping price to come down on the @SitKneelBend recommended 4 channel switch so that I can run multiple cameras.

Thanks, I have a spare chmsl , you know I like spare parts just like you do LOL. I looked at customtronix on YouTube and it looks like that's all they're doing is taking Mopar Grill emblems and chmsl lamps and putting a hole in them. I might as well do both and as I know you already messed around with this what camera do you recommend? I might as well buy a multiples and just do both and then I'll be ready for the switch supplier to lower that $35 shipping , yikes.

In addition, do you have a link to the camera you are using?

I did the exact same thing even though @Mpgrimm2 gave me perfect directions too...Only because you posted this SitKneelBend and asked "ARE YOU SURE? DOUBLE AND TRIPLE CHECK" I went back and checked again.
You were right! Apparently I was actually using pins 14&15 looking at front instead of the back..or vice versa.
Once I had the right pins 24 and 25, that was it. Cargo Camera on! I suspected from the start I had the pins wrong as I stated, but after so many tries I thought I was in the right spot in the plug. Honestly if you had not posted this I likely would not have checked again.
Thank you!

I think I had to give it time but I'm not positive. I'd ask in the AlfaOBD thread with a brief summary just to be sure.All is working well, but I still cant seem to clear these DTC faults even though it's working now. Any reason why or something I need to do?
Yes I did change the "LED CHMSL Lamp Present" to yes after I was getting a DTC for that as well.
U112E - Lost Communication with Rear Cargo Camera
U0264 - Lost Communication with Camera Module
