i'd want the light to come on whenever i start the vehicle. i figured if i attached it to the battery terminals it would always be on, which is not ideal.
the cigarette lighter sounds like it might work, but which wire is it. i've tried looking up electrical diagrams but can't find one.
all i could gather from online was something about a purple and white wire and maybe a red an yellow one without the dots, but those are for different models.
