Even though it is a 12/24 volt plug, I only want to hook up the 24v side, but the plug has four places for wires. On the left side, on the back it has a A+ for a wire and on the same side at the top it has a B- for a wire.

Then on the right side at the top it has a A- for a wire and then below it has a B+. I pretty sure I know how to wire it just for 24volts, but I rather pick one of you more knowledgeable peope's brain.

Do I wire it A+ for the red wire and B- for the black wire?

Thanks in advance.
