There are just two wires coming to the switch and you short out the cable not the switch so that the return from and to the ECU is made permanent simulating a closed circuit in the switch. Since the cable has the female connector it is a simple choice to insert the jumper into the two connector sockets on the cable connector.

As a footnote, the problem with the alarm servicing warnings was a red herring as far as the bonnet switch was concerned. The Volvo main dealer found that there was a siren unit fault, which is not uncommon, and replaced the siren. By the time they did it, I had lost the will to live and didn't ask for the dud unit to see if I could fix it for future use as I understand is possible with a bit of ingenuity. After all this was done and dusted I made the effort to find a way to get my VIDA/DiCE to install, so now I have a functioning bonnet switch, a functioning alarm siren and a functioning VIDA/DiCE.
