Audi A4, ignition switched power

For those who are looking for a ignition switched power line in an Audi, I found one in the Haynes manual.

Note: when you deploy the ignition switched power you MUST use a fuse. 10Amps should be sufficient. It won't cost you much and can prevent a lot of problems. DISCONNECT the battery when working on this.

It is the Black wire (Sw from Schwartz) on the headlight switch lead #1:

"4" is ignition switch, "21" is the headlight switch
You have to remove the left sidepanel to reach (fusebox and) the headlight switch cable/leads. Check here.
