I am trying to wire an Intermatic PX300 transformer to a Pentair SAM 12 volt light. The wiring diagram that was once attached inside the door of the transformer is gone. From my GFI outlet, I have a black, white, and green wire (110v). On the transformer, on one side, I have two black wires, and one white wire, and on the other side, I have a blue, a yellow and a black wire. So, which wires do I connect to the power side, coming from my GFI outlet, and which wires do I connect to the SAM light cord? And, I think, the green ground wire coming into the transformer from the power side, and the green wire coming from the SAM light cord should be grounded to the case of the transformer? I have searched the Intermatic net site and can't find a copy of the original wiring diagram. Thanks for any help.
