Police CAPRICE Electrical problems

Today I Just Bought A 94 Caprice Ex-police Car For Dirt Cheap, Motor Runs Strong And All Is Good Except For Some Electrical Problems, I Was Wondering Did Anybody Know Where I Could Get A New Wrirng System From Because It Lookslike A Lot Of Wires Have Just Been Yanked Out And The Heaer Fan Isnt Working, And When You Turn The Wheel Hard Right The Horn Goes Off, I Wonder Does That Have Anything To Do With The Airba Light Being On, Any Advice Would Be Appreciated

the airbag/horn is probably a bad clockspring. you could try getting the wiring harnesses you need from a bone yard. probably be easier to just fix the broken ones and remove what isn't being used
