I'm retracing both their work, and mine when I installed that light wiring harness 7 or 8 years ago. I think I've got the problem isolated to the relay, but I have to get a replacement to be sure. I'd test it, but apparently they no longer print the wiring diagram on relays like they used to. I don't see why they would have been rooting around in the headlight/instrument area, but I do know they had to disconnect the lights when the crash bars had to come off, so god only knows what destructive forces were marshaled in that effort. Thanks for help, man-- I appreciate it.
