Wiring Diagrams

I need wiring diagrams. As I put on my welcome post, my poor truck had it's wiring harness mangled. I am particularly trying to get the heat gauge back up and running to prevent from doing another head gasket.

I have searched high and low, and all through my Chiltons, but nothing.

Any ideas?

I have the factory wiring manual if you want to give me your email in a pm.
