Wiring woes

[dacanuck]

Okay, so I put my new BFG 285/75R16's on and they look awesome, also lift the truck about 2"!! I try to get it started and just as it's about to get going it stops working all together. Lights come on in the dash but no cranking. Now no dash lights, no headlights, nothing! I have power up to the fuse box under the hood, but none on the inside of the cab. Found the wires to the wiper delay module squiggly from heat. I figure the wires at the key switch have shorted...yes???
