I purchased a Digi-Code Universal CR-2149 to replace a Moore-O-Matic sensor. I am not sure how to connect the wires. The Moore-o-Matic opener has a red /white wire and a black/white wire. The old transmitter has screws marked "back- white+ to emitter" and "red+ white- to operator". Which wires go to which terminals on the Digi-Code marked P2+ and P1- on both the receiver and sender? And I don't understand the clipping of the black and yellow wires on the replacement. I've twice contacted aaaremotes where I bought the new sensor and I cannot get them to respond.
