Re: How to: OEM hitch Install

Hey all,

Yesterday afternoon I installed a OEM trailer hitch on my 2012 Overland, following this thread.

After getting everything back together I am now getting 2 error msgs on the EVIC:

"Service Park assist" and "Service Blind spot"

The only thing I can think of that happened is that I caused some sort of error when I disconnected the wiring harness for the backup sensors....

I'm need of some quick help as I was planning on leaving for my 4th of July camping trip this afternoon. Anyone seen this before?

Re: How to: OEM hitch Install

1st, go into the EVIC and see if the error messages can be re-set. The EVIC may have saved them for a number of ignition cycles if you powered up the GC as you were working on it, before you reconnected the blind spot and parking assist sensor wiring in the rear bumper (yes, there is a sensor for for the blind spot in the rear bumper).

You might try disconnecting the battery connection for a few minutes and reinstalling. But check to make sure you reconnected everything properly first - as in are the connectors tight. Or try some di-electric grease on the connectors.

Did you install the OEM 2-plug connector as well? If so, you might need to visit your dealer for a re-flash. Although I would not think that would be the case.

Re: How to: OEM hitch Install

I just ordered my hitch and will be installing it when it arrives. The only part that has me a bit worried is the removal of the plastic bumper after the bolts are removed. Any tips from those that have already done it? Do you just use some force and the clips will release? Thanks! I called three of my local dealers and all wanted $300 + for just the labor! My closest dealer wants $130 for just the flash. I'll wait until I have it installed and find out who will flash it for a reasonable price.

Re: How to: OEM hitch Install

I did mine last night. The bumper facia is not that hard to get off. Take your time. The only thing I will ad is for removing the top part of the sides that wrap around to the fenders. That part is not clear in the directions and it was hard to get the clips to unclip. Make sure to pull the front edge forward and over the lug where the top screw goes in. The one with the 10mm head. After that you can pull up and outward and the top should unsnap clip by clip. Once I got it started it was easy. Just take your time. The rest is straight forward as the OP has shown. The directions are still wrong for cutting the slots for the retainers but do it like the OPs pics.

Re: How to: OEM hitch Install

Thanks for this "how to". The end result looks far better than some of the aftermarket hitches, (we call them tow bars in Oz). Ive seen some shocking installs by the dealer, where the bumper has been really butchered, and looks very amateurish.
If the hitch is installed after manufacture, what do you miss out on from the "Tow Pack" ? is there transmission cooling or heavy duty radiator that is factory fitted and therefore un available if not requested at the time the initial order is being placed?

Re: How to: OEM hitch Install

This thread was a great help for me too!

I know for the Durango, OEM tow package would have included Hitch and wiring of course, HD Radiator, 230 amp alternator, load leveling rear shocks, and full size spare tire.

I plan on installing the OEM Nivomat load leveling shocks and full size spare. I would like to add a standalone transmission cooler, OEM set up has the typical cooler lines running through the radiator. Not sure if thats included in the OEM towing package?

Anyone add a trans cooler to a NAG1 (WA580)?

I haven't got my computer reflashed yet so all I have right now are trailer running lights, no brake or turn...

Re: How to: OEM hitch Install

Installed factory hitch yesterday in my Jeep, used a flat plastic trim stick to release the clips along the top of the rear bumper facia below the rear tail lights to to front of the wheel well openings, everything else was pretty straight forward, also when bumper is off, there is markings on the inside of the bumper where to cut, made it very easy to cut. M y jeep was prewire already, just installed factory trailer wireing 7way/4way plug, tested after did not all function, had to update vin with tow option and reconfigure jeep with that option to get to work (dealer only for this) if any one needs advice would be willing to offer to help.

Re: How to: OEM hitch Install

Thanks for the great write up and tips... I just got my hitch in the mail, I agree with everyone on here that the oem hitch looks much better than the after market stuff. I was just wondering about the wiring set up... I was looking at the 82212196AB part for about 80$ online plus $120 from my local jeep place to flash it (they are pretty much crooks here). I guess i am wondering 2 things...

1. Does the 82212196AB part come with the setup to mount the plug in the hole on the hitch (4 and 7 pin). Can really tell how clean this will look from pics i have seen.

2. Is there an aftermarket alternative, looks like you can get a generic wiring setup for 25$ that ends in a 4 pin... would this connect to a 56055632AC to get a clean factory look... figure it would save me about 140$ with parts and not having to go the the dealer to flash it.

Thanks

Re: How to: OEM hitch Install

The factory trailer plug 7way/4way just clips into the hole already in the hitch, no extra bracket or parts needed, and looks great, only way to go, if you went with an aftermarket trailer plug, would need and bracket and would have a hole in hitch where factory trailer plug goes,

Re: How to: OEM hitch Install

Thanks to the OP and all the others who posted on this thread. I did this install today on a 2013 Limited and it worked very well. Part numbers were 82212180AB for the hitch and 56055632AC for the 7/4 way light adapter. Just need to go to the dealer and have him flash the computer.

Update: Dealer flash went fine and lights are working. For reference, the code that the dealer had to enter was AHX (Trailer Tow). There are several similar codes, but that's the one the manual called for.
