Vac Question

[Hawaiian Style]

On my 4.0L 88 XJ 4x4 there are two holes in the TB. One of them connects to MAP sensor. What is the other hole for? Am I missing a vac line? :huh:

If you're talking about the pair of vertically aligned holes into which the connector for the MAP sensor is pressed, one of the holes is blind.

Cool, that's what I thought after consulting FSM, Haynes, and Chiltons.

Thank for the response!
