Under bonnet alarm switch - where is it? E300TD

[minijohn]

Hi

I think my alarm problem is either the boot or bonnet not registering as being closed when the alarm is set.

Under the bonnet, I can't find the usual sort of switch - which is probably my problem.

Can anyone with a similar car tell me where it is located, so I could at least find the wiring ?

Thanks

John

OS catch has a microswitch on it for the alarm.
