confusing wiring diagram #49

The changing colors of the wires in the wiring diagram in READ Me make it very confusing. I am legitimately unable to tell which wires go where.

I just reviewed the diagrams in the readme and there are not so much wires. Can you be more specific in order to improve?

Hello. Thanks for offering this helpful library. If I connect external (not from Arduino board) 5V to MQ-131 sensor and heater pins, and also connect MQ-131 ground pin to external Ground, will I still need to connect external Ground to Arduino board Ground?
