help! trying to adapt a '65 Johnson to a newer control

Hi, I have a 1965 Johnson 75 horse outboard with the round electrical connector with about 3/4 of a dozen wires in it to a newer control with the triangular connector with only 3 wires. Is there a source of a cheap adaptor, or at least schematic, or conversion instructions anyone can steer me to?

Thanks in advance,

-Kevin

the control looks like this:

Any idea on the wiring of the triangular plug? It has 3 wires.

Also there is male and female rectangular plugs plugged into each other on the wiring harness near the engine.

There are about 9 wires in the wiring harness coming off the '65 outboard.
 
it is possible. I haven't seen the control for many years. The control that I have has cable shift. Does it also have the electric? And that is what those three wires do? If so, where is the wire for the starter solenoid, ignition, ground/return, etc...?
 
the one I'm trying to interface to must be non-hydro?

Is there a place where there is a rundown/overview of the different styles of OMC shift controls? The features, the theories of operation, the years of production, etc...?
 
Lot of research needed here !-------The the plug in with 3 wires ( red / blue / green ) is likely the one for a trim and tilt. Nothing like that on a 65 model.
 
Kevin.. from what I'm reading, it's not gonna work. You are trying to hook up a single lever mechanical control (cables) to a motor with an electric shift gearcase. You need to find the proper remote control unit.

I went out and looked at the boat again and I think I figured something out.

The wires coming from the controls have 3 connectors. I thought there was only the one triangular one with 3 wires but the other two six conductor ones were actually plugged into each other! But I got to thinking that would make no sense so they probably just did that to protect them from weather.

So its a 3 wire triangular plug, a male 6 conductor plug, and a female 6 conductor plug.

Is it possible this was a universal control that has both cable AND electric shift?

That seems like an awful lot of wires for just a cable shift (but it definitely does do cable shifting too).
 
No such thing as a control that does electric shift and manual shift.-----------------The control with the triangular plug sounds like a control for a 96 and newer motor.--Not likely that you can make it work without wiring diagrams and experience.

anyone got a link to the schematic?
 
A schematic isn't going to help you. You can research this til you are seeing double, and it won't work. Simply put, an electric shift control has an internal switch that send power to the electromagnets in the engine gear case. The controls you have DON'T have the switch. Nor does the wiring include provision for installing a switch, getting power to and from the switch, etc. You have a dual cable mechanical remote. Your motor needs a single cable mechanical throttle / electric shift control. That's it, that's all. FIND THE RIGHT REMOTE CONTROL!!!
