Start relay part link ==>

Your wires will come out of the original overload/relay/start pak but Frigidaire loves to put the little spade retainer locks on there spade clips. You can pull and tug all day long and they won't come out. You have to get a little tiny straight screwdriver, (jewelers screwdrivers), and slide it down in the little square cutout area next to each spade clip and push the little retaining clip while pulling on the wire and it will release and come right out.

You won't have to worry about doing this since the new relay/overload has a different connector, so just cut the old wires and slice the new connector onto the existing wires that you cut off the old overload/relay.
