Require 6v keyed power identification

[1963turnerjohn]

Hello I am attempting to hook up a electric tachometer to my 40 Ford, the instructions require hooking up the power wire to a keyed power source on the ignition switch.

From the picture included here, I’d really appreciate it if someone can please verify the proper pole (1, 2 or 3) that I should used to power tachometer via a keyed source.

Many thanks
John

John ....Does this help you any? You can easily see that the "BATTERY" is power IN. Either of the other two would be "Switched" power. Be careful NOT to get those nuts TOO tight. Hope this helps! Coop

A basic tool even a beginner should have is an electric test light. $5-$10. Touch it to the terminals while turning switch on/off would answer your question. And you can use the same test light on 6 volt and your 12 volt cars.
