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 !

So I've had success ! Kind of...

I ordered a new set of fuses and a new flasher relay.. The new relay is aparently a new electronic instead of the old analog one... meh...
My fuses were all wrong , so i figured I would put the proper fuses in ..

I put the new relay in, all the sudden my hazards dont work when they did before. I call for some assistance which was great.. trouble shooted the issue over the phone untill I got to a point where I was going to re-check the turn signal switch again so we hung up.. I unpluged the turn signal switch and out pops a wire from the connector.. Once I secure the wire into the connector again, put the OLD relay back in.. SUCCESS!! hazards work.. marker lights work, and turn signals work perfectly..
Wierd part is... put the NEW relay in... no workie.. hazard lights come on solid, no flashing, turn signals come on solid with no flashing.. I dont get it...

Also.. not sure if I should be concerned about this or not, but with the old relay back in... turn signals on and flashing... the indicator lights on the tach, both flash .. the L and R... does that matter as long as the turn signals work propperly ??
