i need a fuse box diagram for a 1986 chevrolet cavalier Z24, can i get some help?

try going to a chevy dealer they may be helpful or you could go to autozone and buy a book on your car ,not expensive and tell you everything from a to z .

Agreed, a Haynes manual will have this, or ask your friendly neighborhood mechanic to print one out from Alldata. You can join Alldata, but it will cost more per month than a manual will.
