I have installed my 68mm skunk2 throttle body on my 1st gen b16, and the skunk2 TB only has one port for a vacuum line, which goes to something on the fire wall, there is a red line that came from a black canister and went to the front of the throttle body, there is no where to put this on the skunk2 throttle body, anyone know where it goes or what i can do?
