Where do the wires go on a starter relay?
In case the starter relay has 3 terminals only, connect the thin wire to one of the bolts that secure the relay to the body of the car. Or just anywhere, provided it touches the casing of the starter relay. This is the ground wire, and the negative battery connection, so it can connect anywhere on the body of the car.

Can Autozone test a relay?
A relay can be checked with a jump cable, a voltimeter, an ohmimeter or a test light. If the terminals are accessible and the relay is not controlled by a computer, the fastest method will be a jump cable and a test light.
