| Okay.  Had some more time this morning, so here's the Wideband. I went with the Innovate Motorsports DB-Gauge/LC-1 Kit from Specialty Z as seen here:
 [ http://specialtyz.com/wideband.htm ]
 I chose this unit because I wanted a gauge that would somewhat match the DEFI Display blue readout.
 I also wanted a gauge that goes black when not in use (for appearance and stealth).
 Removed the knock-out plate on the right side of steering wheel:
  
 Drilled a hole in the plate where I could barely thread the gauge through the plate for a tight fit.Also put a piece of 4mm Vacuum Hose on the upper stud to conceal it:
 
  Drilled a hole in the plate for the wires to pass through.Also put a lock nut on the back of the gauge stud:
 
  
 The gauge mounted (with a lot of fingerprint smudges):
  Some more photos of the mounted gauge:
  
 
 Here's where the cord comes up from the Test Pipe, through the fender, and through the firewall:
