21. Remove the plastic cover over the power distribution center on the passenger's side of the fi rewall near
the battery. Not available on some vehicles. If this is the case, proceed to step 23.
22. Remove the fuse from the fuse holder on the amplifi er power wire and connect the power wires to the
accessory lug. Make sure the ring terminal is oriented so that the wire will exit the bottom of the plastic
cover once it is reinstalled. Torque to 9 +/- 1.5 Nm. Fig. 10
23. If the accessory lug is not available, pull back the rubber battery lug cover on the passenger's side
battery and attach the power wires to the lug on the battery terminal indicated in Fig. 11. Torque to 9 +/- 1.5

24. Route the power wires along the fi rewall to the factory grommet on the driver's side, secure with wire
ties.
25. Using a razor knife make a cross shaped incision in the large rubber grommet and feed the power wires
from the engine compartment to the cabin. Fig. 12
26. Install the connectors on the end of the power harnesses inside the cabin. It does not matter what order
the three wires are in on the white three pin connector but the terminal can only be inserted one way. If the
terminal will not go into the connector simply turn it 180 degrees and try again. The black connector should
have a block out plug installed in one side to prevent the power wire from being inserted into the wrong po-
sition in the connector. Push the terminals in until they click and lock into place.
27. Connect the power harness three pin connector to the amplifi er harness three pin connector.
28. Connect the black two pin connector on the power wire to the corresponding connector on the sub-
woofer harness
29. Connect the black ground wires of both the subwoofer harness and the amplifi er harness to the bolt
directly above the hood release lever. Fig. 13. Torque to 9 +/- 1.5 Nm.
