^^ 20" neon light in trunk that has replaced the little light bulb..all wires were snugged up into the old lights housing. Cannot see them.
About hiding those wires.. if i was you, hit up a local auto parts store like pepboys, advance auto, or w/e and get one of those multiple accessories source that can be mounted under the dash and then hide the cords with some black wire loom... Its kind of hard to explain...But make it custom.
