How to replace a double switch (single-pole and three-way) with separate switches?
If you're not sure how the terminals on a switch are used, the best thing to do is to unwire it and test the continuity between each pair of terminals, in each switch position.
In this case, you can be pretty confident about the two-way switch. You just need to find which terminal on the three-way is the common.
&quot;...do I connect the yellow and red Black wires to the single-pole and then leave the yellow and red White wires as they are?&quot;
Yes. Why would you think of doing anything else?
