I just received my Flight Computer Plus

I am trying to hook it up to a TM 1000 and an older Xicoy ICU with the RJ45 connector. Xicoy sent me the RJ45 cable in the package.

Questions:

There are two small metal pins that came with the package that appear to be related to the two pressure holes on the bottom of the unit.
Are these to be inserted in the holes when the pitot tube is not attached?

Is the FC powered by the RJ45 adapter?

Do I connect the FC to the TM1000 using the white central connector?
And if so does the other end plug into the TM's X-bus port?
If that is true, what about power coming from the ECU and the TM1000?

Thanks
