I didn't touch anything up front I swear, but my dash lights and front running lights are out now. My choke/handbrake light and headlights still work. but yeah. More things went out. So maybe a short somewhere with the relay's?
Yeah, I'd start here by first finding a copy to that Supplement so you can correctly identify the relays and wiring. For some reason I though that @2mbb had a copy of that Supplement, but I might be wrong. You could try sending him a PM to see if it is a soft copy...if not, ebay or maybe even Toyota or post in the Classified Wanted section to see if anyone else knows where you can find either a downloadable soft copy or a hard copy...
