I think you need to check the stereo wiring to make sure the green wire (which goes to the radio illumination on factory radios) isn't being used for something else. Most likely since it started with the stereo install. Might be the stereo install specialist thought it was a ground wire.

In the absence of schematic, it is Ok to "guess", but only connect things after one properly verifies, i.e., Physically tracing the wire, Doing resistance checks and or voltage checks. However, this is best left to those adept at wiring/electrical. IF not completely confident about electrical, take your time, wait for competent help, instead of guessing and breaking more things.

A multimeter does a lot more (e.g., you can't really measure resistance with a test light). That's one of the reasons you hear it referenced so often on this forum. Too costly to afford one? No, I don't think so: http://www.harborfreight.com/7-funct...ter-98025.html

I have DASH LIGHTS!!
Bswarm, thanks for the tip, it was in the stereo wiring, the installer had connected the green illumination wire to an orange wire w/white tracer that was then connected a light brown w/white tracer that connected to the white w/green tracer ( through the plugs ) which created a constant loop, I opened that circuit replaced the burned dimmer switch, turned on the lights and success! Put everything back together and all is well stereo included, thanks everyone for the input/info, hopefully this post can help someone down the road
