Ignition switch connector wiring - advice please

The 2 smaller gauge red wires are for the key in buzzer and the orange wire is for the PRNDL indicator lamp. The confusion comes with aftermarket replacement switches. They have a extra smaller black wire in the port where your orange wire was or goes. Just leave it where they put it and ignore it. Remove the orange wire from the cars harness connector so that black wire dead ends. Get you some insulated male/female spade terminals and make the orange wire beside to OEM connector. As for the 2 lil' red wires, you can match them color to color size to size or just tape away to omit the key in buzzer. You may not have a working buzzer switch mounted to you lock cylinder anyway. All the larger gauge wires that start and run the car match color to color.
