Hi i just bought a replacement engine for my 79, 45hp motor its a 72 35hp. thing is it looks like all the wiring has been stripped from the new one i got. i have had a look at the 2 engines and i am going to swap all the electrics over. thing is the top part of the engine is different for example the 45 has lots of wires wrapped around a red disc, the 35 has wires going straight from the top to the spark plugs and 2 other wires that go to a " kill switch" what i need is a diagram on it or pictures or just help in general
