Using the control boxes in parallel most definately WORKS if handled 
properly.  I used parallel T2X/HAM-4/HAM-M control boxes for several 
years in the late 70s and eraly 80s.  

First, I did not connect terminals 4/8 on either control box ... my 
motor run capacitors were all relocated to weatherproof boxes at the 
tower top.  The remaining six wires were connected in parallel ... 
If the motor run (phase shift) capacitor is not relocated to the 
tower top, connect terminals 4/8 on only ONE control box.
