I bought two gauges to help monitor my jeep.

Both are lit autometer gauges that require a 12 volt supply for their function.

I need help finding 2 voltage sources:

One thats hot whenever the headlights are on (not just lows or highs) so that my gauge lights come on whenever the regular instrument cluster comes on.

and another that comes on whenever ingition is on (for trans temp sending unit function)

Im not too picky but would prefer these to be relatively easily accessible.

Thanks so much guys.

 

Where are the gauges going? When I put a trans temp gauge in (in front of t-case shifter) I tapped into the lights for the shifter bezels (can be dimmed with the dimmer switch!) and powered the gauge with a lead from the radio power.
