Yup, that's all there is to it.
ok, no worries, so i just need to run a wire from fwd&rev down to the contactor or relay and then on the other side of that relay take a wire back to the GND (common) pin of the VFD.

No that is not correct you could not use the contactor to switch this it would be to harsh
And for the wiring the Relay basically is just a switch ( 1 ) side you connect to FWD the other Side to DCM and the same for the Reverse it is best to use a solid state Relay then you won't have any noise with the switching to worry about

...bingo. I think you nailed it. http://documents.opto22.com/0510_Std...data_sheet.pdf
Ya those are ac output. They have 20 something vdc on one side and 120v ac on the other side. I wired it up with the contactors as the switches to pull the fwd and rev pins to the gnd/common of the vfd. Works perfectly at this point...
Sounds like you're making progress.
