Mercruiser power trim 1979

[Benking]

I have a 1979 mercruiser power trim that has a single Solinoide on the trim pump and my wires going to the trim switches broke so I am trying to splice the wires and run over the back of the boat and cannot figure out how to hook up the wires the correct way does anyone no the wiring diagram for this ?
