[TowerTalk] Help needed to wire up Yaesu G-800S Rotor cable to the controller

[Scotty]

My Ham friend had a stroke and cannot find his color-code to pin-number paper for the 5 wires coming from the Yaesu 800S rotor on his tower.

What tests using a multimeter, etc. can I perform to the end of the rotor cable in his radio room to find out what color wire goes to which of the 5 pins on the controller box?

Thanks for any ideas you can give.
