Why doesn't your 14 radio show a hu part number and serial number, or SW version? ... Strange

I honestly am not sure what the pink connector is since it was never hooked up on the 13-15 radios and they removed it on the 16-17 radios (we thought it was a separate GPS antenna input). But it's back on the 18 radio and connected (on my factory 18 UAS) and there's also an extra red connector.

13-15 radios...9cfc6af65f573fe22657b720fa6fb1cc.jpg

My 2018 truck connectors and UAQ with the mystery Pink connector. Maybe @00R/T knows (I can't verify it from a schematic/connector info) ...

Here is the system info. I think I took those pictures right after I turned on the truck and they hadn't filled in yet. (it takes a minute or so before they show up)cbac2a5f4013807de03b5584f6ef4366.jpgbc0bb4cd289939f7e4c19e132c586863.jpg

the pink plug is a gps plug .why i have no idea but on my truck 18 with uaq the pink connector harness is about 12 inches long and goes to a gps antenna attached with to screws to the bracket you have to cut out to install a double din radio.

Removed the 17 Ra4 from my 2018 Laramie after 3 days off use with no errors. Must be a setting somewhere or something with having the Sharkfin antenna & correct 2018 mirror that lets it work in a 2018 truck that came with a factory 8.4 UAx radio..

I finally found a 2018 RAM mirror (68342283AA) reasonably priced. I installed it last night . Still getting the error. Next step is to try a shark fin antenna. Really nothing else left?

Thanks for the info. I snapped a picture of the GPS location & Cable PN (68334879AA) for anyone that wants it on my 2018 Laramie while I had the radio out. You can also see the security module.

Thanks for giving it a shot. If you get the sharkfin & extension cable, you shouldn't have to pull the headliner down just to test the sharkfin, just plug it in and sit it on the dash.

Nothing else I can think of, except some setting that is being overlooked in the BCM (maybe not shown w/AlfaOBD).

Mike, do you still have the 2017 RA4 VP4-NA radio? I would be interested in trying it to see if it works without issue.

One last thing I'm going to try, I ordered the pink cable 68334879AA (it was only $14.00).

If this doesn't work I think I will just live with the error :)

I recently replaced my RA2 with an RA3.I installed the radio bezel ( the one that is not ATC). After all of the installation, my auto headlights stay on continuously. Now, I can turn off my lights, however, if I were to leave the light dial on auto as I generally did, the lights will stay on day and night. I replace the sun sensor, thinking that might fix the issue, but it has not. So, my final thought on the issue is that it must be a residual issue with the rear view mirror. I do not have the auto dim mirror (manual) and no 911 assist(although I intend on getting one and seeing if that will cure the problem. if that does not do it the I suppose I could have gotten a bad sensor. Has anyone had this problem? if so, how did you fix it/ I sure could use some help.

i don't think the cable by itself is going to do anything.it goes to a gps ant. not all ra3 or 4's even have the pink connector.the ra4 i am using in my 18 now doesn't have one .and no 911 code.my truck was a factory uaq truck. i've seen a bad air card throw the mirror code.but it seems several people have had the mirror code problem with a retrofit so i would say maybe not the problem.the only other thing i can think of is the uax sales code missing in the bcm.

Just saw this. I sold the 17 Ra4 VP4-NA I had but have another one on the way for an upgrade kit. I really don't think the 17 radio will make a difference for you (vs an 18 radio) but email me if you want to pursue it and we can see if something can be worked out.

A few weeks ago I would have agreed with you, but I found this article outlining the pink connector as a Cell Phone Diversity plug (http://www.wk2jeeps.com/wk2_radios_2014.htm) I think it is intended as a 'backup' in case the purple cable or antenna fails? So I thought maybe the message I am seeing is because there is nothing plugged into the pink connector? Worth a try :)

I have an extra 2016 mirror with mic's if you want to try it. PM me if you are interested...
