10. The last step is to remove your stock hood and replace it with the lighter, vented Shine Auto carbon hood. The louver-style vents allow the heated air to exit the engine bay. Combined with the Pettit TKT intake and Coolcharge III, the Shine Auto hood will make a tremendous difference to the rotary motor. All super high-quality stuff, we'd much rather have these than a girlfriend. | 
11. The passenger-side bin will work for our midget-sized battery. This will require just a little more work before we can fire up the car and get going. |
12. Find a spot in the engine bay to pass the battery's positive cable through. We opted for the rubber seal near the steering column, but there are a few other spots. You can also route the cable beneath the car near the fuel lines. | 
13. Cut through the rubber seal. Be careful not to cut more than you need or harm any wires on either side. With a small hole cut through the seal, slowly snake the cable through the inside of the car to the engine bay. This step may be easier if you have someone who can pull the cable into the engine bay while you push it through. |
14. After you've routed the cable into the engine bay, connect it to the positive terminal. | 
15. Route the positive cable through the inside of the car. This will require that you remove the driver's side kick panel, scuff guard and a few additional interior pieces. This step is fairly straight forward. |
16. Find a chassis ground: We removed the passenger side rear panel. There, we found a suitable bolt to use as a ground. Use a dremel to cut a clean hole large enough to pass the cable through the passenger-side bin. Connect the negative cable there, route it through and replace the rear panel. | 
18. Be sure to tie down the battery and connect the positive and negative terminals. If your doors are open, the dome lights should turn on. Clean up and you're ready to go! |
