Secondary Indicator Light? - ZR-1 Net Registry Forums

KPW · 10-07-2015

On the '90 models there is a "Full Engine Power" light in the DIC. I thought I had read somewhere that the later models still have that lens, but there isn't a bulb in there. True?

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.
