Lol, going by the model code it looks like this was sold everywhere except North America, where I happen to be.

I have found somthing saying the codes F-87 reverse solenoid and F-85 as forward with the same descriptions next to them as I mentioned before.

Single speed coil resistance 6.0ohms so your pretty close there at 5.6.

Do the black and white wires change to a different colour on the main harness side? Possibly 2 blacks with a red tracer, a white and a yellow?
