Need diagram or photo for 91 civic throttlebody

I have a 91 civic (recently purchased) , there is a "tandem control valve" on the back of the throttle body, 1 hose goes from that valve to the actuator.... I have no idea where the other goes... the 2nd vacuum port is broken off the control valve... and with no vacuum, obviously it can't open the valve.

if anyone has a civic with a throttle body, that can take a photo for me, I would appreciate it!

I already tried looking on a honda parts website, and they show the valve, the actuator, but NOT that 2nd hose!!

well, heck here is a photo of what I am asking about... I need to know where the hose that goes to where the blue arrow is pointing to, comes from.
