Trace down the alarm box and cut the wires off. The alarm is not a factory option.
That was probably a mistake. Who suggested that you cut the wires?
disconect or cut the alarm speaker wire
You can not just cut a wire to disable an alarm. You will have to hook that wire back up.
u cut the red wire and plant a bomb
Depends on the type of alarm, but till you find the proper switch find the main power line (Perhaps it goes directly to the battery) and cut it.
The alarm would bo off and someone would know that you'd violated your agreement.
if the alarm goes off and the electrics on the key wont stop it - don't panic at the racket - but simply use the key and manually unlock the Vectra - then put key straight into ignition; alarm may stop at this point but if not then take tyhe last step needed to 'cut it' and merely turn on the ignition/start the car with the actual cut key.
An alarm clock will typically beep for about an hour when it goes off. This is if the alarm is not turned off first.
Depending on how loud your alarm is,it is possible that it may set off another cars alarm.
When you, or your "helper" cut the horn, I assume you mean he cut the wires to the horn. If this is the case, the click you hear is the horn relay trying to send power to the horn which is now disconnected.
