To complete the installation of T-One Vehicle Wiring Harness, part # 118520, there is normally a grommet located close to the installation point that can be used, it is normally at the bottom of trunk cargo area. You would want to cut a small slit in the grommet, feed the wire through and seal the cut you made in grommet with silicone. We do not have specific information for your vehicle as to the location of the grommet. If you find it easier you could run the wire through the interior along trim panels then through a grommet in the firewall to the battery.

If you route the wire under the vehicle, you will want to run it along the frame rail. Make sure to stay away from heat shields, hot exhaust pipes, or the fuel tank. I would recommend using zip ties to secure the wire every few inches.

Once you reach the engine bay, route the wire to the battery. Make sure to disconnect the negative battery terminal. Remove the fuse from the included fuse holder and attach the fuse holder to positive battery terminal. Then attach the other end to the wire that you just ran using the yellow butt connector included as part of part # 118520.
