Stereo & Electronics - ASR question..?

Hey guys, today i took off my radio bezel and noticed I have a wiring harness for ASR, but no ASR button. Is the harness standard in all LS1's, even if it doesnt actually have the system? Im pretty sure i dont have the RPO code on the door, just checking if they all have the plug by the foglights or not.. Thanks

Yeah, my car doesn't have ASR but there's a harness going to the blank plug anyway. I checked my door and build sheet, my car never came with ASR. HTH
