How to: OEM hitch Install
 
OEM hitch install ------ 2 hours

Was looking for a how to for this and could not find one. I almost went the aftermarket route but did not like the look, so I decided to try and do a tutorial. Thanks and hope you enjoy.



Wheel Well Trim

First step is to take the wheel well trim.

There are 2 bolts (1-10mm and 1-8mm) in the wheel well and 2 plastic rivets that need to be removed.

Once the bolts and rivets are removed, start at the top by the door and pull straight out. There are three plastic clips that will pop. Once you get those out the trim piece has 3 clips that can be pressed from underneath. Finish removing the wheel well trim by pulling up on the trim piece.

Bumper Removal

Once the wheel well trim is removed, remove T-20 torx bolts from the wheel well. (Sorry No picture)

Open the rear hatch and remove, two T-30 torx bolts on the lower part of the hatch opening. And underneath there is are two 10mm bolts that also need to be removed.

To finish removing the rear bumper, start at each wheel well at the top and pull towards the front and out. The top is recessed and will require some effort. Then just work your way to the back.

Bumper Cutting and Hitch install

Put the bumper on a sturdy surface (saw horses) and you will see the premarked places that need to be cut out. The directions were wrong in my packet, they did not have me cut out the bottom clips. The best way I found was to drill a starter hole on each side. Then come back with a dremmel to actually do the cut and clean up with a sharp razor blade. The cut doesn’t have to be exact as the trim piece will cover but that doesn’t mean do a rush job. Install the trim piece and make sure everything snaps together.

To remove the cross member, remove a total of 6-21mm bolts pull out and install the tow hitch and reinstall the 6-21mm bolts + 2-21mm bolts included in the kit.

Bumper Installation

The reinstallation of the bumper and wheel well trim is reverse of the removal. The only tricky part is the plastic rivets. If you do not have a plastic rivet tool don’t worry you can just use a pair of dikes and pliers. Pliers to hold and dikes to pull the rivet tight. Or if you don’t want to use either buy the plastic ‘christmas tree’ trim plugs. Also on the reinstallation, the lower bolts on rear are no longer used. I used the trim plugs instead.

I see the long wiring in the last picture. Is that required? I dont have a hitch but have what looks to be a adapter/connector for hitch wiring under the bumper. Im considering this install so just wondering if I need to buy the full wiring or there is a shortcut because of this connector under my bumper. Any idea? Added a pic below

Wow,

Very impressive post! I have tried this install unsuccessfully twice. :confused:

I get stuck :slapfight:'ing to get the bumper off as I feel I'm about to break something. When I get my courage back, I will give it another go. I do have one recommendation for those looking to re-do the plastic rivets and Harbor Freight sells a gun with 40 plastic fasteners for about $15:

You already have the wiring from the fuse block to the rear, but you will need part #2 in the drawing. Unfortunately, I don't know that dodge part number so I purchased the whole trailer tow harness. The last thing you would need to do is to get the cpu flashed at the dealer.

I got the hitch kit and trailer tow harness (I ended up being already prewired) from a local dealer. The kit included everything needed for the install except for 4 plastic rivets, and 2 plastic 'christmas tree' plugs for under the hitch. For the plastic rivets you could goto harbour freight and buy the special rivet tool or just use a pair of dykes and pliers as described in the how to.

Hi Guy's, I also had the wiring under my bumper from the factory, I bought the 7 /4 pin connector but it doesn't appear that the stop/turn signals work. Is this because it needs to be programmed by the dealer or do I need a relay or something. This did not have the towing package but it did have the harness.
Thanks

So the tail lamps work or is nothing working on the 4 pin connector? Easiest way to check this is with a test light if you have not already. Use the ground from the 4 pin to ground the test light then verify each pin, one is left turn/stop one is right turn/stop and the last is tail lamps (parking/headlights on) It could be a fault of your trailer and you think its the car. If you verify that the tail lamps work on the 4 pin but the right/left turn still do not, bring it to the dealer, it might be a blown fuse or the new 7/4 pin could be defective... hope some of this helps.

Yes the tail lights work, no stop/turn. I tested right at the factory connector. I also found there was no fuse in M4 (trailer) and added it. Still same problem. All tow fuses check good.
