I need the approximate and model number of the master cool unit.
Please attach a clear photo of the wiring diagram glued to the inside of the units service panel, it needs to be well lit, well focused, taken close up and straight on.
Include some pictures of the area you are wiring taken from 5 feet away so that I can put into perspective.
Use the 'attach files' link at the lower left of your dialog box to attach them here.
We can go from there.

Phil, this project required a electrician as the ac was only wired for one speed. I have since contacted one and request you cancel my question. Thank you.
