Vac lines on FI motor

[In2Rust]

Just getting the 69 ready to fire up but cannot remember where the MPS vac line goes to? or Where the auto trans modulator vac line runs to?

Anyone able to check their car or know ?

thanks

The vac line from the modulator valve runs back to the engine and connects to the balance pipe hard line that runs between the carbs on non FI cars. If it's an FI engine then there must be a similar facility on the intake air assembly.
