It's a OBD I B18C in an EG hatch, I have an Edelbrock IM and a blox TB that does not have the valve with the coolant lines at the bottom (brain fart and I can't remember the name of it) anyways I was thinking that the nipple in the pic with the black tape on it fed that valve on the bottom of the TB. It's been a while since I took it apart so I was wondering if I would be doing the right thing by plugging off that nipple, or am I completely wrong and that needs to feed something else?

here's how I plan to plug it

Thanks in advance for your help
