Celica Forums General Discussion Interior stereo install wiring question

This picture is of the wiring harness that goes to the rear speakers.

I've looked at every wiring harness diagram I can find and none of them tell me what this green striped wire goes to. Please help?

Edit: Stereo is installed and everything is functional except the parking brake wire isn't hooked up and the amp wires are taped off until I'm ready to install a speakerbox. I'll be hooking up the parking brake wire this afternoon. What is this silly green striped wire? Could it go to the factory amp? Rear speakers seem plenty loud without the green striped wire hooked up they seem to work fine.

So I bought my son a 91 st a few months back. As we start to take out the unit we noticed that the previous owner had cut the original connector leaving us with a cluster of cut wires. Do you have another picture of the other connector or a current diagram so i can cross check? this right here has already helped me a lot.

If so, please share? i need to know what the power wires are.
