Funny thing is the parts ski I bought had the buzzer in it. So I put it in the GTI and it worked about 10 times, then the next day it quit working. I even bench tested it and nothing. So I went to radio shack and got a buzzer. There is 3 connections on the radio shack buzzer, and the GTI has 2. On the Radio shack buzzer it says pos...neg...and pulse???
