The seat belt bolts or any bolts under the rear seats work.

Just make sure you sand it to bare metal first.

I did the same. This way you can hide your wiring this way. You don't need to run a wire to your battery. Running a 15ft ground wire...lol. Your ground wire should not be longer than 3ft.

Here's what you'll need.

1) ground wire (which you probably have)
2) ring connector on the ground wire (which you also probably have)
3) sand paper, 80 grit is good.
4) bolt and a washer

Tools needed

1) A drill
2) Rachet and socket

Instructions

1) Drill a hole on the hump right behind the rear seats (make sure the hole is not bigger than you bolt though).
2) Sand down the area around the hole until you see bare metal
3) Stick ring connector over the hole and put the washer on top, and then put the bolt in the hole, and tighten with a ratchet.

Job done.
