Just a quick question, Just switched the steering colmn and there is this switch on the back of the ignition switch with 2 wires goeing into it. And of the three cars I have all of them the saudering has come loose. Is that switch vital to anything and would it effect the running of the car? Its a square box on the back of the switch and the wires run in with the ignition switch wires and plug in under the dash. Any info would be helpful. Thanks

 

key sensor probably... but you didn't list the wire colors so its hard to say for sure

 

Yea sorry about that its a 2 wire one wire is green and the other is red and yellow and it goes into the small white 4 prong plug and the other two wires in that are black and red and black.
