I am trying to wire a ceiling light to a switch and a junction box and can't tell how to do it right. Here's the situation. I installed the ceiling light about 6 inches from a junction box where a light used to be (the old light wasn't installed so I have no reference to previous wiring.) The junction box has three feeds coming into it, two feeds have black and white wires, and one feed (the feed coming from the switch for the ceiling light) has a black, white, and red wire. All 3 blacks are tied together, all 3 blacks are tied together, and the red wire is capped and tied to nothing. The 2 b/w feeds go off to a row of other ceiling lights controlled by a various switches on the other side of the room. The b/w/r feed goes to the wall switch that controls the ceiling light I'm trying to hook up. The switch box also has another switch in it that is supposed to control the outside light (this also doesn't work). The 2 switches are wired together by a black wire, the switch for the outside light, has two black wires on the other side that go out one feed (there are multiple feeds into this switch box, and 4 white wires tied together), the switch for the ceiling light,has a black and red wire (red on the bottome screw) going out a feed with a white wire (not connected to the switches) that goes up to the junction box (as mentioned before). I believe the power is coming from the switch on the wall to the ceiling junction box and off the other two feeds to the rest of the lights.. HOWEVER this is a guess, it could very well be coming the other way. Confused yet, I am! My question is this... how do I wire the B, W and ground wires to the wires from the switch coming into the junction box?

At you box that has 3 feeds, the blacks tie together(3),Red is your switch leg,goes to light
(Black wire)The black seem to be constant hot, and the reds are "switch legs"that go back to light fixture hot wire.
The source of power will more likely be closest to electrical panel, and a wire(maybe romex)would probably be a black and white wire, possibly at light fixture box, if important, disconnect blacks and see which one has power.
Red sounds like from light switch to light fixture. Light also connects to white and green.
