I got some LEDs that I want to hook up to a 3 position switch that is connected to solid power to keep the lights on as well as hook it up to the dome lights so when the doors open the lights come on. So this is what I want the switch to do:

Position 1 - Off
Position 2 - Dome Lights
Position 3 - On

Anyone have any idea of how to do this? I can pretty much get the constant on one down but as far as getting them to turn on when the dome lights come on is beyond me. Any help would be appreciated!

 

You would need the use of some relays and some wiring knowledge. If you posses neither, then your local car audio shop does.
