Sirius GNSS Pins

I got a Sirius GNSS (M8N) Module (0856A03) and need to use the individual cables of the JST-GH separately. Can you please tell me the order of the cables ? Left to right or color wise.

Looking here I believe this is the order, from left (orange) to right: GND - SDA - SCL - RX - TX - 5V. Is this right ?
Also, are TX/RX already swapped ? Or should I still connect TX(gps) to RX(host) and RX(gps) to TX(host).

Also, what is the voltage of the TX/RX pins? 5V or 3.3V ?
