IMO doesn't really matter whose wiring kit you use the Halogen headlights should be wired with a relay, as well as the door lock solenoids, latch solenoids, and any other hi amperage device you may have.... Relays prevent a lot of overloads (and fire potential) on the aftermarket kits. Like a few others, I think the wiring is of too small a gauge... I like mine a bit heavier then the system requires just for a bit of added protection......

I've wired so many over the years starting with nothing but spools of wire that all the kits look like a cake walk..... I've used Painless, Ron Francis, and a bunch of the smaller companies. Painless is ok, Ron Francis is still the best IMO.
