Well gang, it took me a little bit to get done, but I've gone ahead and finished the wide-band install in my 'vette.

Here's a summary of what was done:

  • Drop exhaust and weld in bung in off-road pipe for WB mounting
  • Mount WB on passenger side, but can swap it to driver's side (with some effort) by swapping the straight pipes from side-to-side
  • Run all new wires for switched (and relay-protected/fused) power inside cabin and wire up the wide-band (and my shift light! )
  • Mount PLX AFR gauge and shift-light in Autometer dual-pod on A-pillar
  • Mount PLX controller in glove box
  • run wide-band and narrow-band outputs to center console for attachment to Flashscan controller


Everything seems to work really well and I'm really happy with the install, even if it did take a good bit of time to complete. I had the car up on jackstands for a few weeks, as I did the whole job by myself on my back. I've posted some highlight pictures here, as well, just in case anyone else wants to use this for ideas.

Special thanks goes to Ross (GMPX) and Steve Bryant for answering the many questions on the 'wide-band' thread! Cheers guys!
