;Audis and VWs have switches inside the ignition that detect
;when a key is inserted. They use it to do things like: ring that
;stupid bell when you open the door, turn on interior lights when
;you remove the key, and (even) power the radio on some VWs.
;If you look through a Bentley, you should see a small power bus
;that is "on when key inserted". It won't handle much load, so you
;may need a relay to drive a stereo.
That's funny. I modified the power to my radio in my old 4000 this way
because I thought it was cool how my dad's 944 did it. You are right.
There is a switch in the key assembly that puts 12V on one of the wires when
the key is inserted. You'll need a bentley manual to find the right one, or
you could just test each one with a voltmeter. I had a 50W radio and it
worked just fine (amperage wise).
Plus, I cut the wire to the buzzer...two improvements in one.
