That Harness Is most likely Obsolete. I would need the year of the truck, and if it's got a Idiot light or standard gauges for the altenator.

Might find a decent one in the wreckers.

Sounds like you fried the Fuseable links.

Possibly easier to replace the wires, and Fuse Links. IMO.

EDIT: As for what you could have fried... Worst case senerio is it fried every electrical device on the truck, from the radio, ignition module, computer to the altenator.

However I doubt it' that bad.
