Is there a way to test a 1116920 horn relay out of the car?

    I have 2 of these never used relays and have a buyer for one.
    Is there a way I can test it with a meter to make sure it works?

    Yes. The hard part is determining which connnectors do what. If you apply 12v to the coil connector and ground to the body, then you will see continuity through the other two connectors. With no power applied, you will see an open through the two contact connectors.

    Wiring diagram should show which wire is which. I assume the trigger ground is the body

    On a google search (and who knows how accurate that can be sometimes) is the 920 relay was for the 1957-1962 era Impala's and possibly other models.

    If that is true, I was helping out another person with his here:

    On ozzie7's last post he said he was not getting an clicking noise and I now wonder if he has his wired correctly or what.

    The relay you have could be tested with an ohm meter to figure out which terminals are what just like you would on some of the aftermarket cube type of relays.

    Here is a link to a site I use a lot and on the right side, scroll down to Relay's and there is info on how to test them.

    The nice thing about those relay's is they do not need to be grounded. One terminal goes to a source of power, grounding another make the relay points close, which then allows power out of the third terminal.
