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 !

"this could take a couple weeks"... Times is all i got right now... with my shoulder bugger'd up I cant do any of the bigger tasks.. soo looking at the wiring is it... I'm going to post a pic of the back of my fuse panel.. you will be able to see the relay socket hanging out and the mnissing relay on the board i'm not sure what it is for... actually I dont know what any of those relays are for becuase it looks different than the diagrams i've found... the socket for the flasher relay is wired rigth into the main harness and I'd have to pull off the lower dash to get at it and I dont think i can do that just yet (shoulder)... i'll go take a pic now.. brb..
