Vacuum nipples on intake runner...
Hey guys, i need help identifying this last vacuum nipple on the intake runner. This is off an 1987 NA

I know the blue is for cruise control.

Yellow is to the thermowax valve.

What does the red nipple connect to?

I just disassembled my 88 GXL intake and this was capped from the factory. I have a manual transmission.
