Route the wiring via the main engine harness access hole, it's located under the rear drivers side jump seat. If you are sitting in the rear seat it's directly behind your left heel. Lift the carpet in that area and you'll find the large DME to Engine harness as it goes through the firewall in that location. Run the harness from outside into the cabin, meaning you will route the small connector end of the harness that plugs into the gauge, start under the car and push that small connector through that large rubber grommet. You may want to pull the grommet out of the tin from inside the cabin, then get the gauge harness through the grommet and reinstall the grommet.

Enjoy!
