I have been wanting to retrofit the central locking safety switch shown in the annex for some time.
This has never been available in the V8 if I am not mistaken.
The picture is taken from the quay of his classic line from the Car-DB.
Unfortunately, the flow of information is zero.

Wanted to ask in the round like this: "Has someone ever retrofitted this feature"?
In the ETKA I did a little research, and I think, for example, that from the Audi 100 of 1994 this switch was available with greater internal operation.
Part number Internal operation: 4A0837019A9XB ( anthracite ) for approx. €21 net.
Part number Safety switch for central locking: 4A096210701C for approx. 30€ net
Where should this ZV switch be electrically integrated into the central locking system?
Anybody got any tips?
