89 pickup wiring diagrams

Does anyone know where I can get a good
wiring diagram for an 89 chevy pickup. I have
a Haynes manual, but they don't show how the
wiring gets routed back to the battery from the headlight
switch.

Thanks

i have a chilton's manual....if you want me to I can fax them to you...they are a very good set of wiring diagrams.

That would be great. Or if you can tell me if
there is suppose to be a 30 amp breaker
between the switch and the headlights?

If you would rather fax, let me know and I'll get
lined up with a fax machine

Thanks a bunch!!
