Wiring issue-wipers quit working

[pritch]

I went to go this morning (snowing) and my wipers all of a sudden don't work. The fuse is blown. I put in a new fuse and it blew instantly. So I know I have a dead short somewhere. The thing is, like most, there is some interesting PO wiring been done. I never was too worried about it, because everything worked.

See the two big yellow wires that are attached to the fender?


I always figured that they were something to do with the camper that the PO had. But last week when I was changing my heater core, I needed a little bit of slack in these wires to drop the inner fender and when I unhooked them, I lost all power. I traced these wires and they run to the after market amp gauge, and apparently they also supply power to the whole system. This don't seem right to me. I didn't mess around with any other wires, just hooked these back up. Everything else still works, just the wipers don't.

I have looked at the wiring diagram, and all the other wires involved and I can't see anything that looks shorted out anywhere. Any ideas? I can find the short OK when I have a little more time, but I just don't get why the wipers and nothing else.
