Need help with Mach Motion wiring, V2XT

I have a V2XT I have had for many years and got tired of paying EMI the grand each time a board went out. I purchased the Mach Motion interpreter 1000 along with Mach3. The wiring is a bit overwhelming. I have all my manuals and can read the schematics sort of... I have most of the AC wired and I'm confident I can wire the encoders and drives. I'm lost on how to wire the contractors, spindle FWD/REV and possibly a lot of things. Anybody who has done this your input would be appreciated.
Thanks, RonO

P.S I still have all the V2XT boards except for the broken FMDC3 which I have already sold. All in perfect condition.
