Some people say the SGM is behind the video, it is not actually. It is inside the dashboard. You got to pull the panel out, you could just use like a peak tool or like a plastic one would be better, thus you won’t scratch off the sides. And the panel is connected with clips that you should remove.

You’re gonna see a module right over here. Unplug the 2 plugs here, now you can plug the Autel Chrysler 12+8 connectors. The other side can connect to any OBD connector from Autel MaxiSys scanners(eg. MS908S Pro) to start reading & writing codes on this car.

The Chrysler requires a 12+8 adapter which is not as easy as the OBD2. The SGM is right in the circle I drew here. Remove the trim panel first, just one clip nice and easy. It is really tight to pull out and on the backside towards the driver’s side of the car.

There are no labels or anything that show you that’s the SGM connectors. But that’s definitely it and that’s what we had to do to get them plugged with 12+8 cable and post-scan done. So just want to share it.

The SGM is right behind the radio, I had to pull this. Let the radio hang and then if you come up in here. The Autel Chrysler 12+8 connectors goes into this black box down here. You have to reach in and push to release and slide them out.

Now you can hook up the 12+8 cable. It took me a while to find it, it wasn’t even obvious once I got the radio out.

To scan this car, you can’t use the OBD port, you actually have to connect this Chrysler 12+8 adapter to the gateway module connectors. As you can see, the gateway module is up there, I have it disconnected. So I just pulled the harness that was actually fairly easy. I thought I was gonna have to take apart some stuff but no, just pull out the connectors. And plug this 12+8 adapter into it. And that does the trick.

After that, connect it to the OBD adapter of Autel MaxiSys Elite, now I can scan.
