Both my 79s have a wiring diagram glued to the inside of that solenoid box.

The black wire goes to grd, the blue wire goes to the solenoid which should be in a junction box (going up the t/t mtr draws more current). The green wire used to come from the t/t switch itself. Blue sky=up,green=grass down. The blue wire coming from the t/t switch activates the solenoid. The blue wire coming from the t/t mtr goes to the solenoid. The solenoid should also have a 12 volt battery wire atached to it. Sorry I don't have a wiring diagram on it.
