I have a copy of the standard 1954 Chevy wiring diagram, but it's incomplete. Consequently, I combined this drawing with my personal notes to produce a colored wiring diagram. You can view this by clicking on the image below.

Be sure to take a look at this diagram... I put a ton of work into it. It is the complete wiring diagram for the Chevy, except for the backup lights (they were not hooked up on my car.)
