(ET) Polarity and Lift Motor

[Lordphipps999 aol com]

Thanks to you people that told me how to hook up the 4 batteries under the 
seat. The wires still had the numbers on them, though very difficult to read. 
But even if they didn't, the directions were enough.
Next problem. I need a front mower power lift motor. The front mower lift 
motor looks just like the power window motors from older GM autos. The GM 
motors are made to take 12 volts. The ET motor takes 18 volts, I think. Would 
this burn out the GM motors? Also, the ET motor has a 3 wire plug and the GM 
motor has a 2 wire plug. Does anyone know how much a new ET lift motor would 
cost?
