okay, thanks curt,SQ GT-S said:01blkgts, I guess you can go the long way. In the Installs section of this site, under Stereo, there are the wiring codes for the GT-S radio. Your best bet now is to cut the white harness off, but try to leave some left on it. Just in case you want to put the harness back on, leave some slack. Using the wiring codes on this site, and the wiring codes in your radio install guide, just match everything up. It's not that hard, it just takes some more time.
There is suppose to be a wiring harness for your 01 GT-S, but I don't know where to get it. I didn't use a harness because I only used the ignition and illumination wires from the stock harness.
