Not sure what you are asking, but here is the answer i think you are looking for.
Your blower has 4 speeds, you put the speed you want for heating on the heat post. You put the speed you want on cooling on the cool post. The last two unused wires speeds go on the two parks. So is you want the same speeds you
had before then put the same two colored wires on the two parks and the same colors wired you had before on cool and heat.
Does this answer your question? The parks are just unused motor leads.
