I just installed the hitch and harness on my 2022 Base 4Xe. The install isn’t that bad you have to remove the rear bumper along with some trim panels. I did the install by myself in just under 4 hours. There are 6 wires that have to be pinned into the factory harness. 2 wires into a plug just above the rear fuse panel and 4 wires into the rear fuse panel. There is also a blue wire that gets run to the drivers side kick panel that is for a brake controller if you have one. If you install a brake controller that blue wire provides power to the 7 pin connector to energize the trailers brakes.

I installed the harness (leaving the wires that needed to be pinned into the harness out but all tucked in and wire tied in place) and hitch in my garage and then went to the dealership where they reprogramed the computer (which is necessary) and pinned the wires into the harness for me. They charged me 1 hours labor to program and pin the wires in. The 12 volt battery needs to be disconnected and the drive batteries need to be deenergized

All in I’m at just under $700 for the OEM hitch and harness and $139 labor. I think it was well worth it as the quality of the hitch far exceeds that of the after market ones I looked at. It also has a place to hold the 7pin & flat 4 connector which the aftermarket’s do not have.

Yes it would have saved me about $350-400 to go with the after market hitch and harness but the only harnesses out there have a flat 4 connector (no 7pin) and has pig tails that go in between the tail light plugs and factory harness. I was worried about the voltage drop at the pigtails causing intermittent problems when the trailer is hooked up. I had that problem with an Audi in the past and I didn’t want to deal with it again. Especially since LED taillights are very sensitive to voltage drops.

Sorry to bump and old thread, but I'm currently fighting with my Dealership to get the OEM hitch and wiring harness working in my 2022 base 4xe. As Ajax did, I installed the wiring kit and hitch (harness 82216041AC, hitch 82219040AA) and apparently the power wire for the CADM safety module gets disconnected as part of the installation. The dealership is telling me (1) that I installed the wrong harness, and (2) that part #82215834AC is the correct part number - which is the trailer brake controller (that I do not need). Interestingly enough, the trailer brake controller instructions specify that if the vehicle does not have the XF2 code programmed, then part#822216041AA is also required (which has been superseded by the part # I installed)... When I explained that to them at the dealership, they don't seem to understand.

Now I know that some of you may have had an issue at the dealership when getting the code programmed - what were those issues and how did you manage to resolve them?

For now, the dealership is disconnecting the OEM harness I installed, adding the sales code, and realigning the modules so everything returns to normal for now. They did this with the expectation that I would be adding the trailer brake controller later, repinning the OEM harness, and everything should work as expected. Well, the damn brake controller I don't need is an additional $300 and I'm already out $700 for today, just to repair the apparent issues installing the 7-pin harness has caused.

Any help you all can provide would be appreciated.

The harness part# I was quoted was 82216041AD.

I was also told by one dealer that there is some jumper wore that is needed, but another dealer said that's not required for the 4xe.

Edit:

I will add, that when searching specifically for that AD part, I can get a google search hit for:

but when you click on the link provided, it gives you a parts not found.

Fascinating, I can't even find the -AD kit available anymore - and last month when I was trying to find -AC, the -AD kept coming up as though it superseded the prior number but the instructions for -AD did not include those for the 4xe. So it would seem that Stellantis is confused about how to aftermarket the OEM wiring kit shrug

I have the 82216041AD at the house. I was able to place an order for it last week and it was delivered to me on Wednesday. I ordered it directly from MOPAR, using various Zipcodes to find the cheapest price and was able to find it no problem. Last week...

Good luck with the install - have you looked at the instructions for that specific kit? There's probably a single sheet in the box with a QR code for the instructions. When I was looking for the kit last month, the instructions for -AD didn't have the PHEV model, so I had to use the instructions Ajax linked.

I only opened the box that everything came in to confirm the overall contents, which was the hitch and the harness. I have not opened the actual box that the harness is in.

My parents wanted to pay for the hitch and installation as part of a Xmas/bday present for my wife and me, so I don't plan on doing any of the labor.

 

[G.Tait]

Well, I picked up the vehicle from the dealership and the cost was just shy of $600 - to disconnect the OEM wiring harness and perform a module refresh to reinitialize the CADM module and clear the codes. The dealer did install the XF2 sales code and politely told me that 82215834AC (brake control kit) is required, that BOTH 82216041AC and 82215834AC are required for the OEM wiring installation to function correctly and NOT interfere with the other systems in the vehicle.

I understand this has NOT been the case for others who have added the OEM 7-pin wiring kit to their JGC 2022 4xe successfully. If anyone with prior experience performing this install and having their dealer add the sales code can chime-in with their experiences it would be helpful, before I drop another $300 for a brake control module I don't necessarily need.

Appreciate anyone's help. Thanks.

See the note about incorrect instructions from Mopar. Hopefully they updated since January. I use an aftermarket controller just fine.

So they were able to successfully install just the receiver and 7-way harness... The tech I spoke to at my dealership assured me that was not possible without the brake controller kit. The instructions I used for the installation of the 7-way harness was K6863106AB (revised from ...AA where there was a pinning error in the CAV connector - Case Number: S2108000205 Rev. A ).

Unless there is another revision of those instructions I'm not aware of - that your dealer is, sigh, I'm still at a loss how to proceed. If you, and others, have been able to have just the receiver and 7-way harness installed without issue, there must be correct(ed) set of instructions somewhere for me to follow when reconnecting my harness.

Thanks for the update!

Did your tech talk with Mopar directly? It took my dealer two weeks to figure it out. It required getting corrected instructions directly from Mopar engineers. They did not share those with me since I didn't do the install.

They claimed they spoke directly with Mopar - whether or not that's true I don't know. I spent most of the morning on the phone with them trying to understand why they were telling me I needed the Brake Controller as well - that the harness alone should function without the brake controller. The Technician (who claimed to have 12 years of experience) spoke to me directly and stated they spoke with Mopar.

Do you happen to have the instructions that came with the harness that was installed?

The instructions off of the MOPAR website for it have instructions for installing the harness in the PHEV version, and its still labeled at the bottom of the first page as April 6 2022.

https://s3.amazonaws.com/rp-part-images/assets/d4c683b648e750350e1904c0c56561bd.PDF

I still need to pull out the instructions for the 82216041AD harness I picked up and compare the two.

I still need to pull out the instructions for the 82216041AD harness I picked up and compare the two.

Inside the box (for part #82216041AC) was a single sheet with a QR code - scanning the QR code pointed me to K6863106AB, dated 4/6/2022 which shows all three models, including the PHEV. Those were the instructions I followed. This lead to my issues with the dealer and the disconnected CADM safety module.

The instructions for 82216041AD are K6863106, dated 4/12/2021 and only show the instructions for the Long Wheel Base model WL75, are a year older, and show the incorrect wire pinning for CAV 6 and CAV 15 in step 32 (which was corrected in a latter bulletin from Stellantis - Case Number: S2108000205 Rev. A)

What a mess - no wonder the dealers are confused. Would be great if someone could chime-in with the correct instruction set.

SOOOOOO, you are saying there is potentially no physical difference between the parts 82216041AD and 82216041AC outside of the confusion with the instructions.

I have the AD harness and just trying to dig in and provide as much information to my installer before I pull the trigger and have it done up.

I have no plans on doing this myself, time constraints, garage space, and lack of all the tools...etc.

Well, the part I ordered and received from Mopar was 82216041AC, without looking at your harness (just the instructions), I would assume it to be essentially the same part - 4 pins to connect (1 to remove and replace) at D6631C and two wires to pin at D3199A. Seems there is some ambiguity as to the proper placement of each wire.

Screw it, I'll probably just order the AC just to make sure there is one less level of confusion.

 

[G.Tait]

These are the glaring differences I've been able to notice:

Instructions for 82216041AD (provided you can find it now as most links either return no results or go back to 82216041AB)
This is dated 4/12/21 and only shows WL75
https://s3.amazonaws.com/rp-part-images/assets/a8145e0b9cdc2276ade9b66d7ca1ce3a.PDF

Instructions for 82216041AC - the ones I used for my install
This is dated 4/6/22 and shows all three models, WL75, WL74 and PHEV
https://s3.amazonaws.com/rp-part-images/assets/d4c683b648e750350e1904c0c56561bd.PDF

JUST comparing the WL75 sections from both -

For D3199A:
old:

new:

For D6631C:
old:

new:

Clearly D3199A is wrong in the older dated directions and there was a Star Online Publication Case Number: S2108000205 Rev. A correcting this issue:
https://static.nhtsa.gov/odi/tsbs/2022/MC-10223054-9999.pdf
The pinning for this connector is correct in the updated instructions.

Now when looking at the diagram(s) for D6631C, you will notice that a pink/yellow wire is removed from slot 34 (to be replaced by a jumper from the new harness).
In the OLD instructions it shows the new harness wire pinned to slot 35 (NOT 34 as shown in the new instructions). There is no Star Case for this discrepancy...

BTW, it was the removal of this very wire from slot 34 and subsequent pinning of the harness wire (identified as 34) back into the same slot 34 that apparently disconnects the power from the CADM safety module and resulted in my issues.

Food for thought.

(to be replaced by a jumper from the new harness)

I did have one dealership mention that there was a required Jumper to be used, but another dealership said that a jumper was not needed because of something they saw noted with some VIN numbers.

I do plan on bringing it to my local dealer to have them do the work, as they have already said that they have installed a few on Base 4XEs. They just don't have any good deals like other dealers on the parts.

 

[G.Tait]

If they struggle at all with the installation, see if you can get some clarification as to what corrections they needed to make in order to successfully complete the install. Good luck amigo!

Just asking a clarifying question here... you did not need to buy the Trailer Brake Controller (82215834AC), which means you did not need the jumper 82216416AB mentioned in the trailer brake directions (which looks like another whole headache in itself), and everything was able to be connected and working correctly (after contacting MOPAR).

You mentioned an aftermarket brake controller... Did you install that, or was that also the dealership?

I am asking because we don't need the brake controller for our use case. It seems that the parts listed on your service sheet would suffice.
