how a relay works

learn how a relay works in real time as I add a custom performance part to what was a overall bland and drab car. All relays work roughly the same, the coil is generally non-polarized, but A1 (if it is so labeled) should be incoming power. the NO and NC contacts are also non-polarized, but remember the comm is the only part that switches.
