I am replacing the light switches and receptacles in an 80's model doublewide. Most have been easy but I am confused about one. It has two light switches side by side. First one controls ceiling light and a receptacle and the second controls the porch light. First one has three black wires - it looks like one from light, one from receptacle and one that connects it to the other light switch via a short wire that runs from first light switch to second - and three white wires, three ground wires all connected to the same switch basically on top of each other. I'm not sure how to wire the new switches.
