Help: Bridge required or not for HC - 05 to Pro Mini

I can't understand how to connect my arduino pro mini,https://www.amazon.in/gp/product/B071ZCHW5P/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

To my HC-05 Bluetooth module https://www.ebay.in/itm/HC05-Wireless-Bluetooth-RF-Transceiver-Module-Serial-TTL/182970488321?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

There is a guide to connect them given here : http://www.instructables.com/id/Bluetooth-Serial-Adapter-for-Pro-Mini/

And this is the given circuit:

I am trying to follow this guide but it is for 5V version and involves shorting the diode on the pro mini plus a divider circuit.

Apparently, there is an obvious difference in the circuit according to my components.

Please help me connect them correctly. I am new to this and stuck at this. :frowning:

Thanks...

The link you provide is for a 3.3V Pro Mini.

The schematic is a 5V Pro Mini.

Which one is correct?
