1G confirm 90 TB ports

[drcolt]

I have a 90 TB. I have searched and searched. I want to confirm which port is what vac line as shown on the attached diagram.
The way I read the diagram is the top firewall side port is the "black", the top port near the front is the "Yellow"
The ports on the side, upper port is the green, and lower port is the "red".

 

[19Eclipse90]

Three of the four ports on the 1990 throttle body are before the throttle plate. The one indicated below is the only one after the throttle plate.

Knowing that, and referring to your handy-dandy factory service manual, you'll find that line which is indicated:

Putting those together with your diagram, you'll see that the "red" line goes to the port after the throttle body. The other three can go to whichever of the other available ports.
