Guage/Ignition Question

[RobbAdams]

I am installing Autometer Guages in the dash of my 66 cuda, a couple of the Guages are required to be connected to the "ignition" There are 5 wires connected to the ignition, what wire do you folks usually use for "Switched Ignition" purposes?

hahah glad you posted this because i've been wondering myself since i'm converting my column shift/key to a non shift no key.

I took my ignition apart to find out for myself since im doing a push button start and looks to be the light blue wire get power from turning the key one click(which i forgot turn what on so could someone tell), then one more click does the brown wire which i believe is all the dash lights, then the yellow is for the starter is seems like. red is the power and black is the ground. if i'm wrong someone correct me.
