Okay so I haven't had lights in my Isspro gauges since I've installed them. I followed the instructions that are online here to use the wire for the dimmer switch as the 12V source for the lighting (Orange wire is what it said I believe?). I found that my dashlights wouldn't turn on so I removed the wiring. The wiring in the instructions were on an 06 and I think its slightly different than the 04s. I tried both orange wires I found for the dimmer switch. So which wire or fuse do I tap into on an 04 for the lightswitch, ie when I turn the lights on, so do my gauges?

Sorry for the long post

 

Hey go to Geno's garage website and there are installation instructions to wire each year model. For an '04 I think it's an orange wire with either a white or brown stripe that will work and will make them dim as well. Check their instructions to make sure. I hope that helps... good luck.

 

its the orange with the brown stripe IIRC.

 

Correct, this is how i did mine, works perfect.
