Connections between Max BR1 MK2 to Mobility 42G

I am unable to find instructions to connect. I assume Wi-Fi 1 and Wi-Fi 2 go to terminal Wi-Fi A and B on the BR1, GPS goes to the GPS terminal, but what do I do with the 4 LTE cables? And is there a specific orientation for the antenna?

MAX BR1 MK2 only has two LTE connections, so connect two of the LTE labelled cables from the 42G and then cable tie the two spares for future use when you move to a higher category 4G or 5G modem later.

There is no specific orientation apart from dome facing up.
You will get higher gain profiles if the antenna is installed with a metal ground plane (ie through a roof of a vehicle).
