Wondering if anyone here has gone through the process of hooking up the trailer TPMS yet. I have a 2018 F250 King Ranch and wondering if the process of adding the trailer harness wiring and wheel sending units is worth the hassle?

 

I have a 11K bumper pull toy hauler. The TPMS sensors in the trailer wheels notified me (by me watching the screen, not a warning) that one of my tires was out of variance with the other three. The PSI was much higher, telling me that something was wrong with that position. The bearings themselves seemed to be OK so I replaced the tire proactively. Once back on the road the new tire had the same PSI as the other three.

The time you spend installing the hardware is probably less time than it would take for you to change a blown tire on the trailer.

 

Yes I ordered it and installed it. I love it.

 

Thanks for the input guys, I guess I am on board with ordering it!

 

^^^ Well, I first thought the trailer TPMS would be a waste but after seeing how the new trucks isolate you from the pulling experience now, I think you could have a blowout and never know it. If you can't tell there is 10K back there the increase from a tire going out will not be noticeable.

 

I ordered it and installed it on my "new" 2018 F350 CCSB Platinum. I think it is completely awesome - almost essential for towing. When blow-outs occure on a multi-axle trailer, many times one tire goes down first (without your knowledge) and then the remaining tire(s) on that side are likely exceeding their load capacity which could lead to a second failure... and that could be problematic from a control point of view. As you inquired about installing it, here's some thoughts from my install:

On the truck side, your kit will come with another module for the 7-pin trailer cable to plug into. This module also contains a new 12-pin plug in place of the Flat-4 connector. Because Ford doesn't want you to lose this Flat-4 connector capability, the kit will also come with a (common) 7-pin to Flat-4 converter that presumably you can carry around in your glovebox. From the back-side of this module, you can depress one of the release clips on one side and then depress the one on the other side and the module pops out. Disconnect the harness from it. Without removing the spare tire, you can reach up and feel the second plug that will now attach to the module. It has a protective cap on it and this protective cap fixes that harness up and out of the way. You can feel around with your hand and find the plug release and when you pull it out from its captive cap, it will extend down and let you plug it into the new module. This whole truck-side work will probably take you 5 minutes.

The trailer side work obviously depends a lot on your trailer design. I started by zip-tying the new 12-pin plug to the trailer's 7-pin plug as the will both now plug it to the truck in the same place. You will see that the TPMS module is 8-10 feet back along the length of wire they give you. I wend ahead and started routing the wire harness under the trailer (driver's side) and when I came to the "T" with the TPMS module I went toward the middle of the trailer and mounted the module there. On my 20" enclosed trailer, the module is almost in the middle of the trailer and about 4 to 5' forward of the axles. As my kit also had the camera, I routed the camera line to the back of the trailer where I mounted the camera. All in all it is a pretty easy job.
