MG Car Repair: 76 mgb electrical problem, electrical problem, test light

Question
I just purchased a 76 MGB and it has a relay of some sort that has been removed from somewhere under the dash. It is a Pektron unit and measures 2"x1.5"x1.5",it has a flat circuit board connector with 6 leads on it. I cannot find a part number on it and don't even know what it is for. Any help on this part and where I might find a replacement would be greatly appreiated.

Answer
Hi Sid, Your description of the relay is of no use to me. The best way to diagnose your car is to try to operate everything electrical and go after what don't operate with a wiring diagram and a test light instead of trying to find a place to put an unknown relay.
Just tell me what don't operate and maybe I can lead you to what is wrong.
