1-What lights are most commonly used on the combo gauge?
2-Does the Tach have turn indicator arrows in the bottom? I can't see where the blinkers would light on the dash.
3- the diagram says to wire a red 16g wire from wiper switch to the positive side of the gauges? It's the positive jumper wire. Can that be just any switched power? We aren't talking the gauge lights, just the gauge power.
