Detailed instructions for connecting external GPS antenna to nRF9160-DK v.0.8.3

Hi,

We are in the process of adding an external GPS antenna to our board and following the guides in the documentation feels a bit risky since names for circuit board parts have changed and sometimes a switch or similar is referenced to in the documentation that do not exist. 

So could we get a detailed instruction for what must be done and how to connect an external antenna to nRF9160-DK v.0.8.3?

Kind regards 

Samuel
