Trailer Tire Pressure Monitoring System

[adrenaline66]

So all parts came in today including @Jimmy07 custom harness which is super nice. I will be towing this weekend but don't have time to get everything done to get a true run. I did however install the rear custom harness and the rear sensor. There are holes in that location in the diagram earlier posted that line up with the sensor and I used that spot. They are just holes with no threads so zipties in the meantime will do or be permanent. I'll have to get to the cab module and find where that goes later next week.

Here are some current pics.

This spot is located behind the bumper area at the right side of where the license plate is. The top two holes were a perfect match for the sensor.

Got the main harness down and opened it up.

Removed the plugs and inserted the wires from the custom harness in their position. I already had a wire in spot 16 so I was informed to place that one in the 35 spot.

Back to factory look except for the new harness coming from it.

Was there a trick to releasing the harness? The white connectors, did they come apart easily or did they break?

Did you need to remove the whole seat or just the bottom cushion?

No need to remove any part of the seat. You could literally get to the connector below the seat or just release the seat backs to fold forward.

All parts came apart easily when pressing the release to each clip. If you’re referring to the tabs that hold the connector to the body, I just used a pry tool which is used on securing pin removal.

Alright, I’m a little lost here: How do you release the seat backs forward? My bottom cushions fold up, but not sure how to release the seat backs? What about the harness on the bumper, how difficult was it to release? I’m just worried about breaking the white clips. TIA.

 

[db252]

If you reach down from the top and behind of each side rear seat, you’ll feel a small cable that you’ll want to pull sideways (I believe toward the passenger side) and it will release the lock for the seat back to fold forward some.
You’ll just want a good pry tool to separate the clip from the body so they don’t break and allow to be pushed right back into position.

 

[adrenaline66]

I’ll look into that, thanks. By body, are you talking about the clips inside the cab or on the bumper? I tried to take a pic of the bumper harness on top to see what wasn’t visible, but had no luck, lol.

I was referring to the clips attached to the framing that holds the main harness in place near the bumper.

Not sure if my truck is different b/c of the eTorque system but the connector behind the rear seat was right behind a little flap in the carpet approx in the center. Other the flipping the base of the seat up - didn't have to do anything else to get access.

TTPMS

I suppose that if my truck already has this adaptor behind the rear seat I will NOT need to buy the “68412666AA - Jumper Cable for TIM Module”?

@db252 can you please reconfirm the part number for the Gateway Module? When I look for it online the picture shows something that is slightly different than what you show in your picture. I get an image of a gateway that has 2 plugs and 3 mounting holes. Weird… hope you can help! (See attached image)

That is the correct part number. Plenty of times pictures shown for reference on parts are not how they actually appear.
In regard to the the jumper cable, I did have an existing one also that will not connect to the module. Go back and compare pics of my earlier post and look at the connector that goes into the module. If they look exactly the same you might be good but wasn’t the case in my experience.

Can this be added to a 2019?

Question: Does anyone know if the small 3" instrument cluster displays the trailer image with air pressure once this is installed and enabled? Or will i also need to upgrade instrument cluster?

 

[fdreyno]

Does anyone know if these same parts will work with a 2022 RAM 3500? Initially I was going to use TST 507 system based upon how the integrated RAM TPMS system worked but now I have researched more I wish the truck had it integrated!

 

[Beardslow]

I have a 2021 Rebel with the trailer TPMS and was thinking about doing this to my wife's 2021 Laramie. I was wondering if anyone has tried the same trailer with sensors on multiple vehicles yet. Do you have to constantly resync the sensors to each truck? Or can they be synced once and the radio frequency from the sensors saved to each truck? I primarily tow with my Rebel but every now and then she pulls our car hauler. It would be nice if she didn't have to reprogram the sensors each time she hooked up to it.

Has anyone found the correct jumper for gateway module in the 2021 1500? I ordered all of the correct part numbers listed however the gateway module has two connectors, not one large connector.

The correct jumper is 68412666AA. The correct gateway is 68493608AA. If you have a gateway with two connectors on it, check the part number on the label. Sounds like you may have gotten the regular truck security gateway module.

Oh okay, I see. So more than likely the wrong part was sent to me. Thank you so much for confirming.
