Selectivend 48 window

[tkutch]

I am a newbie and would like to get some basic help on the wiring on my selectivend 48 with window.  I just purchased a wiring harness that came with a compressor lead.  My first question is how does the compressor lead attach?  I would "guess" it attaches where the red wires are currently sticking out in pic but not sure.  If so does it matter which wire connects to which ends (ex is one of these connections designed to be hot)?  Also how does the condenser fan attach to this system?  The wiring harness just explains attaching attaching evap motor and not condenser.  This is the first time messing with a coolant system so this brings new challenges.  All the other parts are going well and thanks to this board.
