6. Remove two hex head nuts (7) securing the solenoid
to the controller heat sink, place the solenoid off to
one side out of the way.
The original solenoid is
hard wired into the electrical harness.
7. Disconnect the 2 pin connector (14) from the wire har-
ness.
8. Disconnect the 3 pin connector (12) from the resistor
control (13) connector.
9. Disconnect the 23 pin connector (9) from controller by
lifting up on the locking tab and pulling the connector
housing away from the controller.
10. Disconnect the three wires (8) from the electric motor
to terminals U, V and W by removing the three control-
ler terminal screws (11).
11. Disconnect the negative (-) battery wire (3) from the B-
terminal by removing the terminal screw (11).
12. Remove the front two hex head bolts (10) securing the

Installation
13. To install the controller, position it on the floorboard;
making sure that all wires are not pinched or under the
controller feet; and slide it to the back aligning the slot
under the head of the hex head bolt (10). Install the
two hex head bolts (10) in the holes at the front of the
controller base. Torque all three hex head bolts as
specified in the torque table.
14. Connect the three wires from the electric motor. Blue
to the W terminal, Yellow to the V terminal and Green
to the U terminal. Install the terminal screws finger
tight, then torque as specified.
Do not over tighten
the terminal screws (11).
15. Connect the black wire (3) from the B- terminal to the
negative (-), BL-, battery terminal.
Do not over
tighten the terminal screw (11).
16. Install the solenoid on the controller heat sink using
