85 Dodge Ram Van 6cyl.

I have a van that squirrels have chewed the wires in half. Anyone know where I might be able to get a wire diagram or a wire harness that goes from the fire wall to the engine compartment, Realatively inexpensive?
Thanks for your help.

Even though it's a large bundle, aren't the wires color coded? You should be able to go one by one to repair them.

As far as the wiring diagram, check for an electronic repair manual. =edit= you can probably order the repair manual online, or check at the stealership for it.
