It's not too hard to track down a bulb and socket to install there, so what about having it light up when the secondaries open? I thought it could be useful for understanding when they're running while cruising (think Marc H's cleaning procedure), though I could see where having a SES-colored light popping up regularly might be unnerving.
All that said, I'm not sure where I'd hook the indicator up to.
Any thoughts on where might be a good connection? Secondary fuel pump? Or maybe is there a way to tap into the power key for a secondaries on/off signal? Is there a fuse connection that could work? I know a scanner could read this info, but I think it's probably best to stay away from DIY wiring in close proximity to the ECM.
Key things here would be to not screw up anything electrically with the car (!), and to minimize how far any additional wiring would need to run.

Hi KPW,
I had been thinking about the exact same thing and I was hoping someone would chime in who has done this. I've owned my car for 2 months now. It's pretty fast but I would like confirmation that the secondaries are opening.
I am thinking that if I tap the 12v signal off of the vacuum solenoid under the plenum, that is verifying as much of the system as possible. ie: All conditions are met (codes, TPS, temps) and that the ECM is actually commanding the secondaries to open.
