yes, halos are SUPPOSED to be wired into the parking lights.....FIRST thing you want to do is run a small power source to them to ensure that the halos actually work!!! halos EASILY burn out and normally they do sooner than later, so run a power source to them before you install them....and the parking light wire....find your parking lights, and see the wire, there ya go...just trace it back. your best bet though, is to get the wiring schematics from the book, or go to the dealer and get them...
