i am a door access person - i need to add some "key switches" to this fine piece of history.. I have feeling.. (circled in blue) that all i need to do is lift these wires from the post, and install the keyswitch between those two wires, and the post from the call switch.. (where they were)

am i correct? will this work how i expect?

for reference, it seems the oranges wires above are like a common as i see them together. what makes me wonder/what i dont know.. on the left, you can see some green and red which are also wired into the "door close" - im assuming this call switch is a .. "double pole, single throw" if you will..
