So I removed the PO's installed stereo to see if it was gonna be a nightmare to put a new one in. Disconnected battery before doing anything It looked ugly back there so I put the stereo back in, making sure to reconnect the harness into the stereo and the antenna cable. Now the light for the volt gauge doesn't work (but the gauge itself does!), as well as the left side climate control light. The volt gauge is throwing me off cause all 3 RS gauges ground to the same place (the housing for the gauges correct?), and the 3 power wires run straight to the harness... So my next thought was maybe a fuse... I checked all of them, all metal was intact but one looked a little suspect, slight burn marks on the plastic so I'ma replace it tomorrow. Anyways two questions, is there anything I might be missing cause I have a feeling it isn't the fuse, and the picture for the fuse in questions is like a triangle inside a circle... what the hell is that? This is an underdash fuse I'm talking about, and the car is an 05 RS.
TIA

 

It's not a fuse....

 

check the illum wire, I think its white,
