Ignition Switch Hookup

[wb58397]

I have the 704-82750-08-00 ignition switch and need to verify what the the 4wires go to that . There is a yellow, green, black and red wire coming from the plug that attaches to the main harness. Do the yellow/green/black go to the tach? Is the red one just a hot wire to use at my discrestion?

Thanks,

Will

Those are the guage harness leads and connect to tach and other gauges, the red one is for the digital speedometer and not to be used for anything other than speedo.
