You will need a vacuum tube back to the trans. modulator. It should have 1/4 in hose/tube. You need a vacuum hose to the vacuum advance canister on the dist. 3/16 hose. You can hook it to full manifold vacuum. Sometimes to get the best drivability you may have to hook it to a ported vacuum source on the carb.
That alt. is an internal regulated type.
