Unfortunately, Kirks wiring diagrams are old and does not line up to the switches Kirk uses. For example, there is no 58a and there is a 58b. And depending on when you want your gauge lights to come one - it changes the placement of the wire (first pull our second pull out).
I wired my gauges to turn on once the headlights are on (second all out position). First position = driving lights. Second position = headlights and gauge lights.
I am planning to create an updated wiring diagram and post it. I'm almost finished with all of the wiring. I know every car is wired differently, but at least it will be very close to Kirk's wiring on his current builds using all the switches he currently uses.
This is the typical switch Kirk uses for reference (see pic).
