I replaced the factory stereo, w an aftermarket, I got the wiring harness to match, but there is a brown wire that doesn't connect to anything. The wire harness instructions said that could be used for the power antenna but it pops the fuse. I assume that is the issue. Bc when I plug into factory stereo the taillights work, but when I plug in the aftermarket it blows. The wire is not a power or ground according to my test light. That's is pretty much the extent of my knowledge in this area. Owners manual has no wire schematics, I have the internet, but so far have found nothing. Stumbled upon ur site through a thread, hoping u can help?

there is a brown/white stripe wire that goes for battery memory it is fuse 23 in dash fuse box. the brown wire supplies all the lights and whatever else is shown in pic NOT the power antenna. it may also go from heater control panel to a/c. with out actually tracing it back I cannot give an answer further.
