The picture I posted is of the solenoid box side of the wiring harness. The other end is still wired to the motor. The green wire (there is no blue wire) is terminated at the motor and not connected to anything, and as I had mentioned earlier I found another one of these harnesses I had removed from another motor with this set up to find that the blue wire, on the motor end, appears to have a factory sealant on it to stop it from being used. Although, it’s possible that was done by someone else then the factory and this is all just a coincidence.
Nonetheless, I don’t think it will be hard to just make a simple key switch set up just like you find on any of the other motors using the big red plug, and I have plenty of those lying around here anyway. If we do ever find the schematics for one of these it would be nice to have it since I do run across these types of 9.9/15hp motor configurations every so often.
