89 f150 5L AT 2WD

just a question here...electrical problem...no biggie but annoying I checked the fuses over all ready.

here is it...first my dash lights and horn dont work, no cablight either. there is power getting to the horn but have not heard the horn go, not even a clicking sound, so I suspect its a power wire under the dash, or perhaps a ground.
second, my alternator gauge drops and my oil pressure gauge goes all wonky....I would think these are all related to a short somewhere or bad ground...could be something simple so decided to ask first, going to go over it asap. (going to apply direct power to the horn but I have to get at it first)
perhaps a link to some wiring schematics...I dont want to go buy a manual just for the schematics.

for the gauge problem check the ground that goes off the battery to the inner fender

i think it must be a wiring problem under the dash. the horn now works after i sprayed liquid wrench in the ignition and between the column and the steering wheel to free it as it was very sticky and hard to turn, go figure.
