Hi Rudy,
It's important to remember that there is no 'wrong' way to connect your pedals. If it sounds good then it is good!
However if you are not happy with the sound of the setup you described, you could try putting the OCD before the PitchFactor:
Guitar>Fulltone OCD>Pitchfactor>Fulltone Clyde Deluxe Wah>Modfactor>Timefactor>Amp
That will make a difference in the tone of PitchFactor's harmonies. They will sound cleaner with overdrive before them.
