jdl, Just went through hooking up my new turn signal switch for my truck this evening. I had checked all my lights back in the spring, but have found that most lost the ground after I had worked on them. If you have a test light, Find a hot lead and connect a wire to a lead off of a light fixture. I found that these lights ground themselves to the truck chassis and truck bodies. If you can run a hot wire to each light fixture and ground it, you should be able to make the light work. Once you get the light fixtures grounded and working, you may find it easier to get things working. My flasher did not flash till I hooked up a light to it. What I figured out is that the flasher needed a bulb to complete the circuit so it would flash.
