Any update on a Trailer TPMS system?

[jthistle]

It’s the full kit in bag

Ideally I’d prefer to find just the module itself since I already have the wiring for TPMS/CAM/YAW so I could just attach & plug in but can’t find anyone selling it without the wiring/dummy port.

If you don't want it, I'll pay you to ship it here. I'm look for a full kit

However, there is nothing on the Super duty camera+TPMS+yaw set that I installed that would use this additional wire. Perhaps newer camera packages have something additional.

I just installed a LC3Z-1A189-CH (Supercedes -C camera only kit with pro trailer backup) dated Nov 06, 2024. The trailer side cable that connects to the 12 pin bumper connector has only 9 pins populated and the blue/white wire is not included in the main harness.

So the blue/white wire remains a mystery.

But I'm curious if there has been an upgrade with the new part number. Specifically, has the camera improved? The camera in the older kits is low resolution and extremely wide angle. Can you share your experience with this latest kit?

I don't have an older camera to compare it with but it does seem to be low resolution.
The camera in the -CH kit that I bought is PN: HC3J-19H391-CB and the box that it was in is dated 11-20-23 so it was on the shelf for a year before it was put in the -CH kit.

New member here with a 2023 F150 Platinum Powerboost. Can someone help me confirm whether I'm looking at the correct harness here? I want to add TPMS to my buggy hauler trailer - don't care about the camera, just looking for TPMS.

That does appear to be connector C439, and in your case it appears to be 'fully populated' with the wires required for both TPMS and cam.

C439 being what will plug directly into the replacement 7+12-pin bumper socket you'll get with the TPMS kit.

If the 'connector' it's plugged into (under your finger) is simply a 'blank holder' with no wires beyond, that's it for sure.

Confirmed, no wires beyond this. I found a new LC3Z-1A189-B online for ~$250, not too bad. Thanks!

@Broke Richard , here just FYI is a diagram to let you confirm you already have all of the wires to support your need ....

Have Fun!

Alright, got my bumper harness in tonight. Everything on the harness works, except I'm still getting a blue screen on my aux camera on the center display :/ Guess I have a bit more troubleshooting to do.

Wanted to mention a few things from my experience for others though. The job took me a couple hours, but I like to putz and take my time so I don't damage anything.

The backup sensors were tough to get the connectors off of at first. I was pushing on the wrong side of the latch lever. Slide the white part as described, then press on the wire side, not the sensor side, to move the hook. After doing 4 of them - sliding the white part took more force than pinching it to open the clip.

I found it was easier to just remove the license plate lights with the wire harness attached, then remove the harness clip and replace the light. The light just twists and pulls out, but the clip on the harness was tough for me to press to release.

The big connector above the spare tire was by far the worst. It wasn't clear to me that I had to depress the top of the clip before the hinge latch would open, and it took quite a bit of force to do so. Then, when swinging the latch up, the toe of the molding hits the frame underneath it, so you have to pull up on the connector to angle it a bit for the latch to move fully. Also, it does swing a full 90 degrees between closed and open. Here's a pic of what I mean:

thanks for the tip; I couldn’t figure out the big top connection either. And everything was covered in rust proofing film. The sensors and the camera were working. But the plate lights did not come on. I tapped on the exterior plastic a few times and the driver side turned on, but not passenger side
