1967 Barracuda Heater/Ac Wiring Issues

ok guys so there are about 5 thread that have diagrams, besides the 67 book I have in front of me as well as the Color diagram from Ebay. They all are the same, just some are color some not.

NOW where my issue comes from is I have an "extra" on this factory heater/AC box, which in the 66 book calls it a Evaporator temp control switch and I don't know where it wires in, im guessing inline for the compressor

Second is I don't have any blower function but doing testing on that currently.
