Does anyone know what would be the best ground output for an LED light that would operate after the ignition was turned off? I have bought an aftermarket LED scanner and I can't seem to find a correct ground output. If anyone has any idea please let me know, thanks

 

i had neons and had them hooked up to the cigarette lighter wire and used a switch to turn on and off. they could be turned on when my car was off you could try that,

 

Please read the sticky in the how to/install forum. Moving to audio and security.
