TOPIC: older tilt wire diagram

Picked up a 1973 135hp Evinrude with a tilt motor. The wiring is a ball of spaghetti so today is sort it out day. I want to test the unit so I can install it on my older Jonhson 100hp meteor. Looks like an easy swap. It has the tilt rocker, trim indicator meter, two solenoids. It's a bolt on unit, pictures later. Anyone have a clear wiring diagram to follow?
