I followed the video from Autometer on YouTube:
I had a Speed-Of-Sound triple pillar gauge pod, but routed the boost line (I used vacuum hose rather than the plastic hose from Roush) through the driver side grommet. It was a slightly tight fit as I already had the Roush Fuel Pump Voltage Regulator connections routed through it.
For the electrical connections, I soldered the white and red wires together for white illumination during the day and night. I placed these in split tubing and ran them across to the passenger kick plate fuse box and used an add a circuit per the video.
The blue wire is unconnected at this time. This could go to the dimmer circuit if I wanted.
The ground wire is in the same position outlined in the video: right under the steering column.
Works like a charm!
