KWP71 plus this cable, will it work ?

With some info I got on this site I downloaded the KWP71 interface for my 147 then found this link for making a OBDII cable.

OBD2 - RS232 adapter cable (ISO 9141-2) project

Is this all I need to safely connect to the car ? My main aim is to reset an annoying airbag light that came on after removing the passenger seat. Also the cable diagram refers to an external 12V and ground, where does this connect to ? Surely the link between the laptop and car is a straight RS connection ?
