Hey guys i have a 98 c1500 that had the ignition switch go bad in it.I have pulled the steering wheel and replaced the switch but my problem is this i have the switch pluged in to the case and the 4 pin from it connected to the tumbler but there is a small white push button lead off of this switch and i can not figure where this goes. The part number on the switch is a D1414D.Any help would be appreciated Thanks in advance.

 

Sounds like the horn contact, are you sure that you have the correct part?
