Thanks for the reply's... The car is a 1994 C280. I just printed out an older thread via a search- it shows the correct connections to the back of the ignition- I might have switched a couple during installation. But my main question is the two connections on the underside (almost under the tumbler portion) of the ignition, I know one of the two is a wire that when connected activates the buzzer under the dash, my problem is I cant seem to find a wire that connects to the other male plug. I must have spent an hour on my back trying to find a stray wire that would connect, I can't seem to find anything. Is it possible that nothing goes there or am I just losing my mind?
