Astra F - Internal socket

[Turbofan]

Hello,

I need some help in English. I have an Astra F (hatchback, 1991) with engine block heater (Defa) and I want to install a so called "internal socket" (sisäpistoke).

I don't know to pass the electric cable from the engine compartment to the cabin: should I drill a hole, or a usable passage is already there? I need advices in this regard and also pictures of existing installations. So, if you happen to have an Astra F with "sisäpistoke", please post pictures showing the place where the cable enters the cabin (from both sides).

Thanks,

Usually the cable enters from the passengers side. There should be all ready hole for that cable.
There maybe some kind of rubberstopper where you have to make a hole for the cable.
Hope you understand what i'm talkin about
