Does anybody have a wiring diagram handy for a 5-wire,FW490 cw/ccw reversible heater motor? I’ve got blue, yellow, orange, red & black wires on the motor. Did some research online but came back with nothing, but apparently these are universal motors and the wiring configuration determines what direction it turns. I need it to operate cw for the step heaters on my 03-06 Thomas conventionals. I’ve got six of them on the shelf and I’d hate to waste them and I’m out of GR314’s so now’s the time to get them working.

On the motor you splice the black and blue together for it to run clockwise. Then the orange goes to orange and red goes to red and yellow goes to the black.
