Reading wiring diagram: have a question
 

In trying to locate a wiring problem, I know how to decypher wire colors.

What does the number, located in wire lines, before the color, like battery to starter, 3 5 s w , mean?

And how do I know what guage the wires are?

Help is appreciated!!

The 3.5 next to the color code is the size of the wire in mm.

The sw means schwarz whitch is German for black.

Ah ha!
 

Oh, I see I missed a decimal!! The numbers are the size of the wire! Thank you very much!!

Is there any way to know how long the wire is? Should I buy in "bulk" or how do I tell how long an individual wire is?

Again, Thanks!!
