Taco ZVC404 wired with ZR/ZC

Hello all, I am replacing an Argo AZ-4CP (burnt out) with a Taco ZVC404. My confusion is wiring an incoming ZR/ZC for priority controlled elsewhere. There was a spot on wiring block on the Argo, but inexpensive Taco complicated matters for me. I checked Taco's website and video instructions but still not sure, any help would be appreciated.
Thank you
