lost ignition key

[awthacker]

I just installed the new ignition switch, but when I turn the key to ON, it energizes the starter. I must have wires mixed up, but can't figure out which ones. It's a 3 position switch - OFF, ON, & START.

Here's what I wired: S - yellow; C - purple/white stripe; A - purple; M - black; B - red; and the terminal with the rubber cap is also labeled M. I thought I had gone wire for wire but missed something. The old switch is slightly different than the new. Does anyone know what I missed?
