My front parking sensor box has a basic ON/OFF switch...so to turn the front sensors on when necessary. That switch is basically either ON or OFF, interrupting a +12V wire.
I have an unused PORSCHE switch for "rear window heating". Could that work, if i connect the wire to PIN 1 and PIN 2 (the top ones, close to each other)?
Sounds simple, probably isn't

Thanks for your help in advance!
