How do I connect the analog video board on my emac?

There are two set of wires connecting to the analog video board, a red/blue set and a brown/yellow set, which I don't remember where they go. The plugs are the same so it makes the confusion, The only difference I can tell is the location, they are both on the right side of the board, one is on the upper corner and the other one is lower corner. Can anyone help solving this problem?
