Dan---post a picture of the instructions--or give us something to go on.

If English is a second language for you do the best you can.

Main hot wire to furnace will need a pig tail to line 1 (possibly labeled line h on board) and one wire goes to the transformer. That's three main hot wires in one wire nut.

Other than that and on the low control voltage side, the cool terminal, labeled Y on the board, will have one wire to the condenser and one to the stat. Two wires there on one terminal.

Pics would help. Not only the diagram but the unit and board and all wires.
