Underdash LEDs
Looking at wiring up some LEDs under the dash. I’d like them on only when the car is gone. Anyone know which wires to tap into? Thanks.

I used to have some that were connected to the light in the push start button, if that's applicable to you. That way they were on when I got in the car before I started it, and when the headlights are on.

BigTuna's suggestion is also a good mention if the ground circuit isn't BCM controlled. I bet it is, which isn't to say you can't do it, but there is a risk of damaging the BCM if done improperly. The radio wiring doesn't carry such a risk. It also gets complicated if you want them to fade in and fade out like the dome light does. That requires tapping into the interior light system's ground wire from the BCM which again is a bit riskier. |

I would be happy if they just come on and stay on when I start the car
