How to test a used '70 headlight motor relay

[CornDogsCharger]

I was wondering how you would go about bench testing a relay for the 1970 Charger headlight motor.  This relay usually mounts under the dash and has the two light green wires connected and the two dark blue w/ tracer wires connected.  My friend needs one that I have but I wanted to make sure it worked beforehand.  Thanks

energize blue and test for power on one of the prongs, and not power at the other... thats closed position... the energize blue and green and prongs power must switch between output prongs

needs chassis grounded

sounds logical?
