turn signal help please, for the electically in-experienced.. Options

Background:
The PO of my 73' 2.0L said that he never actually drove the car. He picked it up to restore and then got more involved with his MG's ( he has a sweet MGB with a mustang drivetrain in it , and a couple more under covers) .. anyways.. the turn signals dont work.. in the glove box i found an extra relay socket, and a 4 prong relay... hanging out under the fuse board is another of the same socket I found in the glove box.. I'm assuming that some PO wired this thing in to get the turn signals working.. the signal lights all come on when I turn the headlights on ( tail lights AND all the turn signals ) when fliping the turn signal switch, nothing happens.. no dash lights.. no flashing...

question...
I've never really needed to use a multimeter before, so i'm totally inexperienced with this.. I want to know how to find out if this socket is infact for the turn signals ( so I can just get a turn signal relay ) or find out where to check the wiring with the multimeter to see where the disconnect is happening..


Since My shoulder is out of commission right now, I cant do any heavy work at all, but testing a circut with a multimeter is doable. I've downloaded a couple wiring diagrams, but it all looks a bit greek to me right now...

Thanks in advance for the help !

I looked up under where teh fuse panel is mounted.. I can see the switched on the dash but other than that i just see some wires.. no relays, etc.
