Nothing happens when I turn the key

Drove 20-25 miles, shut off and next day nothing worked, the battery was fully charged. New starter a month ago. I noticed rubber hoses at purge canister were chewed, replaced, fuses good look at wires. Under the dash by parking brake pedal noticed a yellow wire broke from a screw together type connector mated with a pink on the other end. I repaired it, still nothing. Truck listed above has 300,000 miles.
