Someone changed this truck over to 12v in the past and added a couple of under dash gauges. Wish I knew who it was, so I don't hire him by mistake sometime. What a rat's nest under the dash!
Got most of it cleaned out and was able to follow one of the lights down to the flasher, so yeah, one for high beam, one for turn signal.
Think I'll be able to ditch the add-on amp gauge and go back to the stocker, but I'll have to keep the add-on fuel gauge until I get the stock tank back in the truck.
