Yeah, that’s the telematics box; the “TBM” on the sticker is “Telematics Box Module”.

It looks much like the Wrangler one. If it behaves like the Wrangler one, it will notice the antennas being unplugged and will throw OBD codes and display errors on the uConnect.

On the Wrangler, those antenna connections are:

1, purple, “cellular antenna 1”
2, pink, “cellular antenna 2”
3, blue, “gps antenna”
4, brown, “satellite radio antenna”

The connectors they use are called “Fakra” connectors. They’re all slightly different, so you have to have the correct lettered connector if you want to replace the antenna with a dummy load:

purple: D
pink: H
blue: C
brown: F
