Why go to the trouble of wiring into the car power?

I saw an aftermarket accessory that operated a garage door opener when
the headlights were flashed. That wouldn't be difficult using a relay
if you wanted a stealth installation. You may need a cap in series
with the relay sense lead to make it momentary operation; otherwise
the opener would stay on when the high beams are on.
PS: If you still want to use the Passport power supply, check to make
sure the current (mA) is high enough for the door opener.
