I have a 77 Allison that needs some wiring. The power trim gage is inop and the hour meeter is disconnected. I am the third owner and the boat has been used very little. Runs great with a 175 Black Max Merc.

Call Allison at (865) 983-5920 Bill or Darris can help you.
It's possible the hour meter was added later.
But the wires for the trim should be the same as newer models.
There was a diagram for newer boats that someone put together on the Allison owners page.
