Your data is coming in on the middle pair, -24 volts DC is coming in on the next outside pair for the second KLM and -24 volts DC on the next outside pair.

From the wall you use a three pair cord to KLM #2 and then you could run a two or three pair cord from KLM #2 to KLM #1 and then you could use a one, two or three pair cord from KLM #1 to the phone.

Because of the way you have to run the cords in their channels, I turn the phone and KLMs upside down, cut cords to the right length and put ends on them. If you are very close on the cord length, everything stays snug and the KLMs hug the phone.
