Where can you find a fuse diagram for 1989 f 150?

Answer 1

Answer 1 - "Finding" or Obtaining Fuse Diagrams for Any VehicleThere are many ways to get access to fuse diagrams including:

• Dealership Parts Departments can provide order forms for ordering vehicle service literature from the Publisher of the vehicle's documentation, or
• Ask an owner of an identical vehicle to allow you to view his/her Owner's manual, all of which usually have such a diagram, or
• Ask an owner of an identical vehicle to allow you to view the fuse box cover or panel which usually has a diagram or list indicating which fuse serves what circuit, or
• Ask the Dealership Used Car Department for permission to examine the Owner's Manual, or fuse box cover or panel, for fuse and circuit IDs of an identical vehicle, or
• Occasionally, but seldom, your local library may have specific vehicle documents that will contain the info you want.

There are probably a few other sources that I have forgotten. Good luck.
