Are the front parklamps supposed to remain on with the headlights? Half pull on the headlight switch is just running lights (front park lamps and taillights). Pull it all the way out and headlights come on, tail lights stay on, and front park lamps go out. Is this normal or do I need to replace the switch? I waited to post this till the new wiring harness was in, just to make sure there weren't any shorts in the old-pieced-together-with-old-extension-cords-and-anything-usesable wiring harness present when I got the truck. Thanks!
