What is the wire gauge of typical car electrical systems?

Gague wire size for ECU's, Joint Box, witing harnesses, etc.

A side question...where would I find that size?


Cars use several sizes depending on what the load is. It is safe to use 14 gage wire (can be found at any parts store) for most things except starters, alternators and main power to fuse blocks.
