New Tow Mirrors installed...cant get full functionality

[codyjm28]

Hello, I have been scouring the internet for answers, no luck. I still cannot get my reverse guidance lights to work after installing tow mirrors. Turn signals, power fold, adj. arrows change when mirrors are up/down, but no reverse guidance lights. I have read you need to turn on cargo light, in reverse, for them to turn on. No dice. I have made "tow mirrors present" in alfaobd, and turned on trailer reverse guidance, but i dont think that is for the lights. I think that is for the trailer reverse assist knob which i dont have. Any ideas? Using android phone for alfaobd. Thanks!

Not sure if the HD Rams are similar enough to the 1500s, but they say there is a button on headlight switch for the. If you didn't replace the headlight switch, then maybe they won't work?

From the other threads I have read, there should be an option in radio to enable them, but I cannot get that option to show up even after multiple hard resets. I feel there is an option i need to turn on in alfaobd but I am not finding it.

Thanks for posting the settings info. I've got a set of tow mirros on the way to swap out on the current vehicle. Just saved me some daylight hours and likely sanity.

Edit: Yep! Had to load current vehicle in Alfa, then forced it over to the 2020 2500. Selected those options listed above and everything worked perfect.
