2 unknown wires

hi I have a '03' Silverado 5.3L 4x4. There are 2 wires coming from the passenger side firewall. 1 has power the other is a ground. They accidently touched and my 4x4 system trouble came up on the dash. I checked the fuse and it blew put a new one in all set. What are these wires for?

How was the fuse that blew marked? That should lead you in right direction.
