Roush Boost Gauge install help

I am trying to find suitable power connections for my Roush Boost Gauge. The instructions call for a 12V Accessory Power for the red wire, ground for black wire, Accessory Power 12V for white, and 12V switch power (packing lamp) for blue.

The two places that immediately come to mind are the headlight switch panel near the steering wheel, or the interior fuse box at the passenger side footwell.

I would prefer not to splice, so the fuse box it is, but when I accessed the fuse box on the passenger side footwell, there are no open fuse spaces. They are all occupied.

Is there a fuse map of what these go to? I can pop in an add-a-fuse.

If that's the case, what is the pin out of the headlight panel? There is a dimmer module, and two other connections.

That might be exactly what I am looking for.

Time to bust out the multi-meter.

Update:

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!
