Great automated engine re wiring identification (by color)
 

In my quest to figure out how audio systems work, I found this great little auto-engine that outputs wiring colors by its function (i.e. 12V, 12V accessory, front left speaker, etc).

Sorry 01 and above, it only works for cars built from 1970 to 2000.
