Require 6v keyed power identification
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
