Question about Electrical Supplies
My Cooper (Eaton) OS306U has red, black, and blue wires (and green for ground). Both of my existing 3-way switches have a Common and 2 other wires. I would really just like to pop out one of the existing switches and wire up the 306 without rewiring the other end but I cannot figure out which OA306U wire is Common.

Hi and welcome to FixYa,
My compliments on the KP-500.
The black wire serves as common/return for the green/gray speaker wires. Yes, the black wire should also be grounded to the vehicle as it is the power ground and is tied to the chassis/body of the stereo.
Good luck and thank you for asking FixYa.

Find the Hot wire:
Your switch has 2 wires. One of these wires is Hot, and one goes to load. Disconnect wires from switch. Turn on power. Do not stand on wet surface. Test each wire to bare copper wire. When tester lights up, that is Hot wire. The other wire goes to load.
Hot wire goes to Black timer wire
Wire to load goes to Red timer wire
White wire connects to white wires that are twisted together
Bare copper wire connects to Green wire from timer
How to connect white wire to white wires that are twisted together.
a) Strip white timer wire so you have 1-1/2 " of bare wire. Stranded wire will wrap around other wires easily.
b) Remove wire nut. DO NOT UNTWIST wires.
c) Hold all whites together so bare copper lines up. Wrap stranded copper around the twisted wire.
d) Replace wire nut, or use larger wire nut. Twist real tight. Do not use tape. You can solder the connection.
e) When done, pull on white time wire to make sure it is held tight. Push whites back into box.

Your screw terminals are 2-brass and 1-dark.
Dark screw is considered 'common'
Leviton shows a 3-way 1203-2, but not 1201
Wiring diagram indicates that pilot light is ON whenever switch has power.
Check your instruction sheet that pilot light is supposed to turn on-off with Load.
I don't think it is, without additional terminal on switch for neutral wire.
And then it would only work on switch located closest to light.
You can wire this type of thing separately.
Buy ordinary pilot light or indicator light from WW Grainger.
Look at diagram on following image:
