1976 - Main Relay (efi/fuel pump)

I think I hosed the relay by mis-connecting the two leads. With connectors in proper place, nothing happens.

Can't locate a combo relay (looks like a combo) in Houston, but Auto Zone can get separate fuel pump / efi relays in about a week.

Any ideas on what else I might have screwed up or where I can get a replacement?

Thanks for the help.
