Modem Card (Sierra MC7354) with QOTOM Q20332G9-S10 - How does GPS connector work?

Hello everyone!

I currently have a QOTOM Q20332G9-S10 with opnsense which I am using as a router and due to my mainline internet having outages I want to setup backup wireless internet via 4G. To do this I purchased the Sierra MC7354 which opnsense advertises as being supported (see Configuring Cellular Modems — OPNsense documentation ).

I have purchased the modem card, LTE/4G/5G antenna as well as the various cables (SMA, U.FL) that feed into the MAIN/AUX part of the card. My question here is how does the GPS connector on the modem card work? There is a nano SIM card slot on the QOTOM board, see photo of board below (its to the left of the VGA connector, labelled SIM1)

But how do I connect this sim card slot to the GPS U.FL connector on the modem, i.e.

I am kind of new in this, I recognize the MAIN/AUX connector as its the same for WiFi cards in laptops (which I have replaced many times and its quite easy to do) but its the GPS one that I am unaware of.

As a final question, can this modem card be placed in any M.2 slot or should I use a specific one?
