stock to autometer wiring

Thank you guys for this post.
I was actually going to start one on same subject, but used the search function and found this post.

I am doing the same thing on a a 73 Duster cut the plug and wire Auto meter gauges in.

Just to clarify the brake switch, blue/white trace to + on the light and 20g black is used for the ground. Correct?

Yes, That is the way the schematic reads. Redfish helped me with this as I originally had it grounded with everything else but it needs to be by itself. Black is the ground which goes to the push switch which is bolted to the steering column in line with the brake pedal.
