MGB 1978 MGB distributor wiring

[ghatchie5866]

Drove this sweetheart since mid 90's without electrical issues. Then lost power 2 times, No power to plugs. Replaced coil but no power from aftermarket Lumenition or distributor to plugs. Installing new distributor with no amplifiyer and discarding the Lumenition. Old distributor had three wires with one running from tach. New one only has two wires. Cannot figure out how to wire this up. 1978 MGB. Coil tests good. Any suggestions
