2026 JT OBD Port

[firemedic2714]

I second the SGW extension cable if you're ever going to have to unplug it to return to a dealer for service. It makes it an almost effortless 2 minute job.

So I watched your video and they are super easy to find in your JT.

However, I have a plastic “wall” there above the OBD port and I have a feeling that the security module may be behind that.

See the 6.99 mark in my video for where the “wall” makes an appearance. (Apologies for poor video work.)

I’ll try and find the plugins again, but it’s becoming a lot of work.

Hmm. It looks like you could be focused too much on the left side. Try more towards the center, it should essentially be directly above your OBD2 port, but inside, if that makes sense.

Is there a hole underneath that “wall” to shove your arm into?

Maybe you’ve got some unicorn? Lol

My OBD port is mounted way over of the left side against the left side of the footwell. I tried looking above but that’s behind the plastic wall and no visibility up there.

I’ll try again some other time and maybe take even more panels off.

I think you need to come at it from below.

OMG, so helpful!! Thank you!! That gives me much better guidance to try again now! Thank you!

There's also the reasoning that you might be TOO DAMNED TALL to fit underneath there.

Absofreakinglutely!

I had to practically stand on my head earlier facing the footwell to even get a glimpse under there!

Rapidly coming to the conclusion that the JT might be a tight fit for me if I’m doing anything other than laying in the bed. Even then it might be a tad cramped!

Yep,my 2026 JLURX was a pain to get to.My 2021 JL Willys was easy peezy.There was very little room and hard to see it in the 2026.

I couldn’t really contort myself to see the SGW, but I was able to follow the cables to the box and disconnect by feel. I have spent a lot of my life working on things I couldn’t see. It would have been nice if they moved it closer to the center kick panel, but I don’t think FCA wants you messing with it.

I tried the grope-in-the-dark approach, something my wife says I’m pretty skilled at! And following the wires with my fingers. But no bueno. The wires coming out of the OBD go in to a big taped up bundle of wires and then they seem to go behind a panel or that plastic wall I keep encountering.

And that’s 100% the conclusion I came to, they purposefully made it harder to work on and out that stupid plastic wall in there. I am pretty sure my SGW connection wires are behind there.

Thats a bummer. It was really easy to get to on my wife’s ‘21 JLU. It was harder to get to on my ‘24 JTR. So looks like we are following the trend towards harder to install external modules.

Yes, I believe so. Harder for the consumer to mod / mess with stuff which seems like a general trend anyway.

So I’m not sure what I’m missing, but I have a OBD module for JScan and a security bypass cable. See below:

When I plug the OBD module in to my JT OBD port it comes up on the JScan app and lets me know I need the security bypass to change settings. Fine, that was expected.

So then I go to plug in the security bypass cable and I cannot for the life of me find the 12 & 8 pin connectors that the bypass cable plugs in to. I searched all behind the steering wheel and even pulled off the plastic trim panels below the steering wheel. No sign of them. See pics below. I found the footwell lamp and then a lot of wires tucked away but that’s it.

I followed the wires from the JT OBD port you can see in the pics and it seems to be a single wire coming out from it that then goes up in to a wiring harness and in towards the dash or something.

My question is, does anybody know if the ‘locked down’ one 2026 JTs and removed the extra 12 & 8 pin cables that allows you to plug the security bypass cable in?

If so, can I get something like an in-line security bypass cable so I can use my OBD module and JScan?

I'm an old jeeper in a new '26 JT Mojave. And this is very unfamiliar to me,(what Y'all are discussing)...
Let me see if I'm understanding any of this;
The red jumpers in the bag connect to "all" available OBD ports on the driver's side under & up behind the dash. Then you connect a module to the remaining port, which will allow you to access and change hidden features within the jeep. Do you read and make changes using your smart phone or tablet ... or does the screen on the infotainment center provide the visual access needed to see & make changes?

Thanks for entertaining a NOOB

So I’m not super knowledgeable on the OBD stuff but basically you can buy a module that connects to the OBD port under the steering wheel. It lets you see diagnostic information about your vehicle like temps, pressures, settings and such.

If you get certain modules and accompanying software it lets you make changes to the settings on your vehicle. Maybe you want to turn the seat belt warning chime off, or stop the fog lights dropping out when you put your high beam on for example.

To do this you need to bypass the regular OBD port as it has a security feature built in that won’t let you make changes. So you get the security gateway cable (SGW) in the bag pictured in my post and plug the two ends in to where your OBD port wires connect under the steering wheel up in the bowels of your Jeep.

Once that bypass cable is plugged in you can reattach your module to it and now you can actually change the settings on your Jeep and have them stick.

At least that’s the short explanation for the route I’m going using a Bluetooth module and JScan software on my iPhone.

They are several other options for modules / software as well which I’m sure others can explain better.

There is a box under the dash called the Security Gateway. It blocks your ability to attach to the OBDII port and make any changes to the setting in the Jeep’s computer network. The reg cable thing is a bypass. It allows you to remove the cables from the security gateway and gives you a working OBDII port that you can then make changes through depending on the adapter you attach and the software you use.

I use a Bluetooth adapter and JSCAN on my phone to change tire size and other settings. When I remove the adapters and plug the security gateway back in, those settings remain. You can leave the adapter attached and do some “live” settings, but I have a Tazer for that.

If you want to keep the ability to change things on the fly without accessing an app, the Z-Automotive Tazer JL Mini is the way to go. It does not require the red OBDII adapter. It attaches directly to the cables after you unplug the security gateway. You controlling through steering wheel controls and a dash menu. The Tazer acts like another computer module in the Jeep’s network, intercepting and sending commands. You can do a lot to it that the Jeep wasn’t originally programmed to do.
