If I get motivated at some point I'll look into swapping the bulb (or just ignore it so I don't go down some rabbit hole), but for now all issues are resolved thanks to one fuse change for the ECU-IG. The ABS light turned off once I actually started and ran the truck tonight.

Thanks for the list of things controlled by the ECU-IG, like I said earlier I never knew all of those lived somewhere common and could be affected by one fuse. I suppose with all of the issues popping up so suddenly a fuse would have been an obvious place to check (in hindsight)...I was having nightmares of chasing short circuits when it happened.

I hope you never leave the forum so you can continue helping the electrically-challenged such as myself. Where do I send beer money?


(now this thread can sink into the forum depths before people see that I can't check fuses and I lose all internet credibility)
