convertion

:? HELLO I AM TRYING TO CONVERT A 180 ELECTRIC MOTOR THAT I HAD IN MY SCHWIN S180 TO A 750WATT MOTOR I BOUGHT AT SCOOTER CATALOG BUT THEY HAVEN'T BEEN VERY HELPFUL WITH CONNECTING THIS. AFTER BUYING REALIZED I NEEDED A NEW CONTROLLER SO I PURCHASED ON AT THE SAME PLACE, NOW THAT I'VE GOTTEN IT HERE I DON'T KNOW WHAT TO DO IT SEEM THAT THE WIRING ISN'T THE SAME, AND OF COURSE THERE IS NO PAPER WORK WITH THIS BEING THAT THIS MY FIRST TIME COULD SOME ONE OUT THERE HELP ME... LOST AT THE DRAWING BOARD
