Bought a 83 z/28 and mice had ate through some wiring while po had in storage. Completely stock never modified not even aftermarket radio. Have found and fixed all bad wiring by replacing wiring and plugs where chewed though. Yes even replaced grounds. turn ignition on and rt parking light comes on and stays on. driving me nuts Help!!!

 

Figured out. 2 wires inside bulkhead were chewed thru. bypassed and works great
