I just finished installing a new headunit for my 03 Alero. everything works well, howeevr i noticed my gauge lights are not working properly. Out in the sun I can barely see the gauge lights but at night it works fine. I did not wire the dimmer wire of the radio to the alero harness...
I used metra 70-2003 wiring harness.... and referred to this page for the wiring diagram

The diagram says dimmer/illumination is NA so I did not bother connecting it to the harness...
Thanks for your help
