Rear-only Park Sense Module Location

[sg88]

Hello, Please help!

In a prior post (https://www.jeepgladiatorforum.com/forum/threads/rear-parksense-retrofit.33254/) this question was asked but never answered:

FOR THOSE WHO HAVE THE SYSTEM OR ARE IN THE KNOW, CAN SOMEONE TELL ME WHERE THE FACTORY PARKSENSE MODULE IS LOCATED?

I can see if the vehicle has both front and back sensors, the module sits in the front bumper on the right. But for only rear sensors (which I think is a thing), where is the module located?

I plan to add the rear parksense to my 2023 Gladiator Mojave when I install a new rear bumper (Rough Country tubular rear bumper https://www.roughcountry.com/product/jeep-tubular-rear-led-bumper-10647) which has the places drilled for Parksense sensors. I have acquired the wiring harness (Mopar part 68406683AD) which is very, very hard to find. The remaining components are easy to come by, but the module for rear park assist is one of the rare parts that is shown independently and not as a part of a location diagram (https://www.moparpart.com/oem-parts/mopar-parking-assist-module-4672769ae), there is no location diagram that I can find.

Since the proper wiring harness connects the sensors into the general body wiring harness, the module must sit remotely, maybe plugged into the green "star ports"? A company Infotainment makes an after-market system that utilizes a separate wiring harness altogether and places the module behind the glovebox. But their system does not use the native wiring harness and their unit includes a programing unit that is not necessary with the Tazer JL which I have so I am trying to create a more OEM system.

Any help is greatly appreciated.

I think you are talking about the ones on the back of the tail lights. Remove the light and you will see a molded in location for them. I hope this is correct?

Others please correct me if wrong.

Maybe so...I thought those were only for the blind spot monitoring, but when I try to build a Gladiator on the Jeep website, I find that the "ParkSense" always comes with the blind spot monitoring.

Anyone else can confirm this, and if I add the modules to my tail lights without the special mirrors will the sensors still work on the bumper?

FOUND IT on the JL, probably the same location on the JT. It lives on the back of the driver side lower dash speaker pod:
see it at 05:33 on the following video

Actually finding that was a false alarm...When I searched the part number of the module from the video it came up on E-bay as park assist control module (https://www.ebay.com/itm/2248492980...6VxMVUFDQgFugtPnqciphiKUGn6Q|tkp:BFBM1MbNoKBj)
...but as I searched Mopar online parts sites to confirm I was not able to link to that part, and I believe that the module is really the network secure gateway control module, so my search for the location of the park sense module continues.

its located at the passenger rear, inside the jeep, not in the tail light cavity. you'll have to pull that plastic cover off back there to see where it mounts up. If you are wanting to mount your park assist module back there, more than likely, the studs won't be there. You can buy them from mopar though. I chose to mount mine in the front under the driver's dash to the backside of the canbus security module. I installed front park assist on my 2019 jeep and it made more sense to put it there.

According to the drawings, rear park assist harness goes from the rear drivers side bumper, behind the rear tail light penetration, up the drivers side to the front seats, across under the driver's seat, under the console, under the passenger seat, then back the passenger side to the module mounted in the passenger rear. :O

Thank you, and I finally found the details. I asked Crutchfield's technical department since they have looked at the electrical systems of almost every vehicle and are incredibly helpful if you are looking to upgrade your stereo. I have used them on a number of vehicles over several decades. In any case, as you note, the module for the rear park assist sits on the back wall of the the cabin of the gladiator on the passenger side. The nuts to attach the module to the studs that are there are available with the module itself. I have yet to have the chance to move my rear seat and pull off the back fascia to see if the connections are there in my body wiring harness, but I am thinking that they are not. Next step then will be to figure out how to build the connections as I am not a wiring guy and do not know the suppliers for the proper connectors. I have attached a few diagrams that show the location including off a vehicle that was being modified for something else but the module can be seen in the photo.

I will add more information and a parts list as I learn more.

I installed front park assist on my 2019 jeep and it made more sense to put it there.

I was considering doing this for my JT since the euro-spec ones have it available from the factory, so I'm sure some of the wiring is there and some AlfaOBD programming would bring it to life.

Can you describe how you did it on your JL?

Wow, that location sucks, right next to the factory CVPM but thanks for figuring it out. I’ve been avoiding taking that panel off but it looks like the ONLY way to add front park sense to a vehicle that already has the rear park sense is to get to those connectors.

If you’re talking about the star connector block on the passenger side, it can be accessed without removing the back panel. There is a small access panel covering it. Obviously the module would need a different home if the entire panel isn’t removed.

“Star connector”? Not sure what that is. I Can see the edge of the module and the first of the three connectors going into the module after removing the 2 screws and small shelf(?) behind the passenger side rear seat (where the optional Bluetooth speaker would be). Is there another way to access that module I’m not aware of? The problem is I need to access all three connectors to insert those connections into the new 4-connector module 68441032AC unless I’m reading the schematic wrong.

On mine there is a trim tool only access panel higher up. I’d say 6” x 3”. Just a guess without measuring. I’m not out there, but can take a picture later.

I think you’re referring to the CANBUS connector. Yes that would also be impossible to get at that module from there. A pic would definitely help, thanks.

I will when this is over.

How would that be displayed on the screen?
i have it on the rear as well. If its easy to add id do the front as well
