Alright so I have a 2001 Chevy Impala and I'm trying to install an aftermarket stereo. The factory harness has been cut out so I'm having trouble figuring out which wire is what because it's not matching some diagrams that I have read online. I've been reading that the constant 12v wire is Yellow but there is no yellow wire. And that the other 12v switched is orange but there are two orange, if someone could redirect me to the correct forum and give me an accurate diagram for 2001 Chevy Impala that'd help tremendously. Thanks all, Ivan
