This is why walmart and others sell a wiring kit that plugs one end into the stock wires and the other to your radio, One hot ware goes to always hot wire for clock and station presets, other goes to switched ignition so radio goes off with the key.
I see what his problem is. I have a 2004 Envoy XUV. The one brown wire is a continuous power feed and the other brown wire won’t power the aftermarket radio. I also have a wiring harness. On my 3rd one for this “make”. The harness is off all of them. So I moved the wires around. But I need to find an ignition wire to splice and run off of. And that seems to be my issue now. I need power directly from the source. I think the second harness that we don’t use is what sends the signal to send power to the other line but not sure.

Go to www.installdr.com and search through the diagrams in there, the site is easy to use, all you need is acrobat reader installed on your computer to use the site, it has a full explanation on every wire color and what it is

Get a AA battery, solder a wire ti each end. This is called a "popper"
Hold one wire of the AA on one speaker wire. Tap the other AA wire to the other speaker wire. The speaker will make a "popping" noise. Mark the wire as to the location, and so on. To determine polarity (- or +) you must be able to see the speaker. If it jumps UP when you "pop" it, look at the polarity of the AA battery.
That is the proper polarity of the wires. If it sucks IN, when you "pop" it........you're backwards. If this is over you're head......$30 @ a stereo store and it's over!.....Have fun.
SOURCE: How to connect radio wire harness
Easiest and most painless way is to get and adapter harness from any Wal-mart or auto supply store. Has easy to follow diagrams and tells where all wires go. Also makes for easy, no cut, removal in future.
SOURCE: trying to splice wiring harness for trailer lights
there is no need to splice wires especially on a 02, you can get a trailer harness at any autoparts store that will connect into your original harness. Dont get me wrong you can splice into it but do you really want to ??
