Where does the hose from the distributor go to on a 1985 Chrysler fifth ave?

This must be a vacuum hose, with a connection to the intake manifold, at rear of carb.

This must be an after-market distributor because the original "Lean Burn" computer did not have a vacuum advance distrib. The vacuum was connected to the computer that controlled the distrib. advance. these setups, one made by Mopar, kit #P3690426, by passed the computer and is vacuum operated.
