DIY - add Auxiliary switches to a 2016 RAM 2500 Tradesman

The OBDLink MX works fine to use with AlphaOBd? Don't need the MX+?

 

The OBDLINK MX version worked great. I did not need the MX+

Thanks so much for the info!

 

So I’m newish to the forum and want to do this upgrade. I can work my way through most electrical projects but wanted to see what gauge wire you recommend using going from the connector to the relays? Thanks in advance.

 

I used 14 gauge wire from the aux switch to the relay and 12 gauge wire from the battery + & ground, battery + runs through my auxiliary fuse box to the relay. I'm sure it's a little overkill.

Great thanks for following up

 

Finally finished installing these in my '17 2500 last night. Only problem I am having is the Aux switch CSM doesn't show up in my radio (it shows up in my 7" cluster under the commercial settings though) and when I go through the commercial settings menu and check the "last state" of a switch it pops up with an error, says something about checking the owners manual.
It is also possible to get everything from a OEM setup and wire it like OEM (you could add a PTO this way as well), I'll take some pictures and get a list of all the terminals and connectors I used if someone is interested in doing the same.

 

I’m in

I’m interested if you have a write up on it

 

Sorry, been meaning to do this. Hopefully I'll be able to get some pics / parts list this week.

 

Just to clarify, you are saying that if I found a parts truck with the Aux switches installed I could wire it up myself?
