After soldering my cruise control amp on the 560SEL and reinstalling it, I thought I was being clever by cutting the wire up there on what I assumed was that super annoying seatbelt buzzer from hell. To my amazement, the buzzer still works and continues to annoy me. What is this small round bluish component under the dash that I cut the wire to? Nothing seems broken. - Mike

PS - Cruise control works great now.
