Adding front and rear parking sensors?

[Quietpeen]

Hey, I swapped my front bumper for a Westin Outlaw. I thought I put all the sensors back in the same orientation but I am getting continual warnings when I drive. The pass side seems ok but the front is super sensitive and randomly senses stuff that is not there and the driver side is almost constantly jumping from not sensing anything to warning red. I might have swapped the drivers side sensors (very possible actually). Would this cause the funny action? Anyone know where I can find out if I have the right sensors in the right location?

Harness part number is: 2021-2024 Ram 1500 - 68489203aa
The 2 sensors on the drivers side each have 3 wires. One of them has Gry, Y/W, Blu/W the other is Gry, Or/W, Blu/W.
Right now I have Gry, Or/W, Blu/W as forward facing/front.
I have Gry, Y/W, Blu/W closer to the tire in the far left/drvr position.

Truck is a '21 Bighorn 1500DT. Thanks for all the info so far!

on my truck(21 TRX) all the fronts sensors are the same part #. The only difference was the bezels they go into which I guess changes the direction they point slightly.

If this is the bumper you have it's very possible the sensors are just picking up the bumper itself based on them being recessed slightly and having the tubes in front of the sensors View attachment 191230

Yep. That's the one. Man, I hope its not picking up the bumper. You'd think they would have figured that out before now. It's been out for many years. I hope someone can help me out with either a schematic or pinout for the harness I listed above so I can rule out misplacement of the sensors themselves. Are the sensors sensitive to clocking as far as "is there a top and bottom"?

Any idea where I could find the schematic or pinouts for the connectors on the harness?

I thought that was the case but even in the PDF directions for adding parking sensors in this very thread they list different part numbers for clocking left or right of the connector housing.

In case it helps anyone. Here is the parking assist schematic for 2021.

I'm not sure it matters which sensor is where, at least in my 2020, all the sensors were the same. And the plugs on the harness are pretty self explanatory on which sensor they go to based on length and location of the pigtails of course my aftermarket bumper doesn't have the two sensors on each side so close to each other.

I definitely saw a thread(maybe on the TRX Forum) that said which way they are clocked is important. I will try to find it, but I think the outer two both sides the plug was pointed toward the center of the bumper and the inner two the plug was pointed toward the edges of the bumper

found the thread and what I said above is correct. Outer two both sides the plug is pointed toward the center and the inner two are pointed toward the bumper edges.

Thanks. That's how I have it.

I ended up just taking them all out, cleaning the connectors, reinstalling them to the harness and mounting them to a stick and testing them one by one. Everything worked so I reinstalled them and assumed the problem had to be with the positioning. I just drove the truck and whichever one acted up I moved it's position until it worked. the movement was literally a degree or two and maybe a mm in one direction or another. Its hard to be precise with the way they mount. Eventually after a couple adjustments they all started working like a peach. I halfway wonder if they don't just do some sort of self calibration.

Hi All,

I am working through the process of adding park sense to my 2024 Ram 1500 Limited. I am hoping to get some help on the parts list needed for this. I found the VIN of a truck that is the same trim but has park sense, Limited with Limited level 1 package. I am finding some differences that I want to make sure are not an issue with the process described in this thread. I do want to caveat my truck does come with air suspension, someone had mentioned air suspension in reply so I want to just throw that out there.

The biggest thing I have in question is the rear park sensors. The limited with park sense has 6 sensors in the rear. All of the descriptions in this thread only have 4 which seems to be Laramie and below trim models. The limited level 1 package also comes with the Park assist package which might be the reasoning for the extra 2 sensors in the rear.

I still have questions about the harnesses and other wiring but want to start with the components first. Should I use the Laramie or below parts without park assist or should I use the limited parts which appears to be slightly different but closest to my model? Thank you for any and all help!
