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.
