    • 2 M8x1.25 lock nuts
    • 2 Fender Washers (not shown in picture)
    • 2 Threaded tie-down rods (not shown in picture)

STEP 1

Remove Trunk Carpet, Trunk Deck, Spare Tire and Styrofoam insert on left side of trunk.

 

STEP 2



Position the battery box as shown in the above pictures to mark for holes to be drilled. If you purchased the PHR Trunk Deck with the battery cutout, you can also use this to position the battery by placing it into the trunk first, then slipping the box through the cutout and then removing the trunk deck.

The box should be positioned against the frame rail and about 3/8 of an inch from the edge of the grommet shown in the picture.

 

STEP 3


Using a marker or grease pen, mark the drill points through the battery box bolt-down holes.

 

STEP 4


From underneath the vehicle, remove the exhaust heat shield below where the battery box will bolt down. This may require removal of the exhaust, depending on the type of exhaust is installed.

 

STEP 5


Move the battery box back out of the way, and using an 11/32 drill bit, drill a hole where each mark was made.

CAUTION! The rear hole is very close to the fuel cell. Take precautions not to hit it or puncture it with the drill bit!

 

STEP 6


Bolt the battery box down to the floor using an M8 Bolt fender washer and nut.

NOTE: The floor of the car is not flat like the bottom of the battery box. Bolting the box down will pull the floor up to the box and will slightly screw the box as it is pulled slightly out of shape. As an option, you can use a spacer or add padding to add support under the box to reduce the floor deformation or box deformation. We have had good luck just bolting the box directly to the floor and allowing both to be pulled together.

 

STEP 7


Insert the threaded tie-down stud into the holes in the floor of the box and stand upright to stay out of the way of the battery being set in.
