Default Battery cable question

Hi everyone!

I’m replacing the connectors on the end of the wire and I noticed there is a thick cable and a thinner cable on positive and on negative.

What are the thinner wires for?

If you know what gauge these wires are supposed to be, please share!

Thank you in advance!

Positive cable - Starter and Underhood electrical center
Negative cable - Block above starter (G106) and frame (G104)


Your service manual has a table that explains wire sizes in detail...located in "Wiring Systems"

The schematics will show text on both sides of a wire.
Left side of wire is size and color
Right side of wire is circuit number.
