Taurus fan plug wiring

Finally got my new radiator in and mounted my 2-speed Taurus fan and just buttoning up the wiring. I have a brand new fan and I got the factory plug from a buddy but I am not sure which wire goes to what and I am not sure if I hook it up backwards if I can short out the motor or not so can anyone tell me the wiring for this plug, hi, low, and ground? I have a 10ga solid blue wire on the left side, a 12ga brown w/orange stripe wire in the middle and a 10ga solid black wire on the right side.
