2. Place the battery in the battery box and mark the height of the flat top of the battery on the box.
3. Remove the battery and use a ruler and marker to mark a line

” below the point marked previously.
Mark this all the way around the box.
4. Using a razor blade or tin snips or scissors cut the top of the battery box down to the line marked.
Battery box cut down to size.
5.
Replace the battery and place the crossbar hold down over the battery. The crossbar should be able to
go over the sides of the battery box.
6. Position the box with battery on the passenger side lower part of the car trunk. Push it forward
against the aluminum step and just far enough over so that the crossbar does not touch the side.
7. Use a marker and mark around the base of the box on the aluminum.
8. Hold one of the “J” bolts vertically through the crossbar hold-down and locate the ¾” tubes below the
aluminum that will be used to fasten the “J” bolts. You may need to slide the crossbar or battery
around in the box to line up with the diagonal tube in the trunk. We have included 4 bolts for the
battery. Three of these will be able to go into ¾” tubes while the forth can only go into aluminum. If
you wish to run all four bolts use a fender washer or weld an additional tube in for the bolt to go into.
Note: In SCCA, as long as the battery does not move it is ok. NHRA rules specify two
⅜ ” bolts as
required. Mark the locations of the bolts on the aluminum so that holes can be drilled.
9. Decide which way around the box you would like to run the battery cables and make sure there is
enough room for them. There should be enough room in the current location to run them on out of the
box on the wall side.
10. There is more than one way to route the battery cable to the front of the car. One way is to Drill a ¾”
hole through the aluminum step next to the wall in order to pass the positive battery cable through.
Pass the eye end through the aluminum then push on some of the plastic grommeting around the
aluminum edge before pushing through the remaining cable. Another way is to pass the cable through
the aluminum next to the shock tower, again using grommeting on the aluminum.
11. Follow the manual instructions on the routing up to the front of the car once the cable is through the
trunk.
12. Locate a point on the frame for the ground cable. You may drill another hole like the positive cable or
attach it inside the trunk.
13. Without moving the crossbar or battery move the battery box to the middle of the trunk.
14. Take the battery box top and press it down onto the box over the crossbar.
15. Lift the top of the box off along with the crossbar that should be wedged inside.
16. Mark the location of the holes used for the crossbar bolts with a marker.
