I've wired the air/fuel gauge (purple wire) to the grey/blue wire at the wiring harness at the drivers side kick panel. Still only the one light all the way to the right comes on. No light show (I know it's mainly for show). I jumped the purple (voilet?) green wire at the main PCM; same results. Is there a way to check the gauge? I'm having problems with my tune for my new supercharger; could that be the issue?

Thanks,

Kenjo

 

I had issues with the lights on the same gauge and also giving me erratic readings. AM replaced it under warranty.
