A friend of mine has a 1978 Mustang and i suppose it's way before they
introduced a standarized adapter. the back consists of power cords and
connectors to each individual speakers. Anyone who have a connection
scheme or knowledge of an adapter that fits?

best take a trip to maplins.co.uk they do an ISO with free leads at the end
to wire as you wish.....
