Hello, thanks for visiting 2CarPros. To test the relay you will need a fused jumper wire and a non fuse one. You will connect the fused wire to the positive battery terminal and the other end to pin 1 of the relay. The other jumper wire will go to the negative terminal of your battery and pin 2 of the relay.
You'll then need to use a multi meter set to continuity or the lowest ohms scale and place one probe on pin 3 and the other on pin 5. You should have continuity or 0 ohms resistance. I'll post pictures below showing the terminals.
