I'm in the process of adding front sensors to my 2014 Ram 2500. So far it looks like it will work. My only issue is that I bought a bad batch of non-functional sensors off eBay (verified that they were bad via AlfaOBD), but I ordered OEM ones that should come next week.
The tricky part is getting the harness that connects the bumper harness to the module. I had to make one by ordering a Mopar connector repair kit (
68030130AA) and splicing it with 9 ft of wiring to an 8 pin pigtail (ordered from findpigtails.com). Once I replaced the rear only module with the module that supports front and rear (68141530AJ), the truck recognized it and the "service front sensors" message came up. I still had to use AlfaOBD to get the Uconnect to give me all the options and to get it fully working.
Last thing I'll need is the dash button panel with the front parksense button, which I ordered.
So, for people who have a 2013-2015 Ram 2500 or 3500 or a 2013 Ram 1500, it's possible to add OEM front parking sensors, provided you have the supporting mods.
