Fuse Box Locations

The fuse box in 73-87 Chevy trucks is typically located in two main areas:

1. Inside the cab: The primary fuse block is usually found under the left side of the dashboard, near the driver's side. This location provides easy access for the driver to check and replace fuses when needed.

2. Under the hood: A secondary fuse box is often located in the engine compartment. It's typically positioned near the battery, on the firewall or fender well.
