Wipe any debris or oil that may have settled on the over/under brackets. Set the motor into the under bracket so that the two threaded holes in the bracket’s end face the same direction as the motor shaft. Pull the ground wire over the top of the rear mount as shown and place the over bracket with its tabs also facing the front of the motor. The ground wire should now extend out from between the over bracket and the motor mount. Place and tighten the four bracket screws so the motor fits securely between them. It should not be possible to rotate the motor once it is mounted in the brackets.
