splicing in a new control box

[peiserma]

Hi everyone. Looking for some advice.

I want to replace my engine control box. I have an older 86 Johnson GT150. It has the red plug. I have not found a direct replacement, but maybe this one could be made to work http://www.offshoremarineparts.com/4-5006180.html.

Is it as simple as splicing wires? I have a wiring diagram for the motor. Could I cut the plug off the old control box and splice into the new, or is it more compicated than that?

Are the throttle/shift cables standard, or is an adapter required?

Or does anyone know where i can buy a directly compatible control box? That would be simplest.

Thanks for any feedback.
