So just put some LED spotlights on my Samurai all good simple job as I don't want them connected to the headlights or running lights. But I have a switch in the dash which is backlit so will drain the battery when the car isn't on. My question is: Is there a switched live in the engine bay I can link to so the dash switch is only on when the engine is on?

Thanks in advance

Look for a Black with white tracer under the dash or in the engine bay. That's an ignition live.
