I was looking at some schematics and have 2 questions:
1. How does a relay work?  I know it's some kind of switch but thats all
2: IN these schematics, it shows where +12V goes into the system but
doesn't show where -volts goes.  Should it go where the schematics show
ground (I think it's ground, It's a inverted pyramid made with horizontal
lines or a tornado) eg.
