2000 Sonata wiring diagram color code?
 

As I mentioned in another post, I'm looking to tap into the driver's
door switch on our 2000 Sonata GLS to install a headlight warning
buzzer. I looked at the courtesy light schematic available on the
Hyundai Webtech service and if I'm reading it correctly, it looks like
what I want to do is attach to a wire labeled "0.3 L" going from that
door switch to terminal 5 on the JM06 junction block under the dash.

Anyone know what the key is to the color code on these schematics, I
could not find it anywhere. What does "0.3 L" signify?

I have already located a connector under the dash that is +12V when
the exterior lights are on -- the buzzer is installed, it just needs
to be hooked up to the door switch to be operational.

0.3 indicates the wire gauge, and L indicates it's a blue wire.
