Default 67 dash electrical

Does any on know what this yellow wire is for? I have the instrument cluster out to change out my lamps to LED.
Thanks

These schematics are from the 1967 Assembly Manual. The only "yellow wire" I could find in that area of the dash, powered the radio. It was also the only single yellow wire connector I could find in the schematics. Not sure I'm right, but maybe you can see something I missed.

Thanks that makes sense, because I have an aftermarket Stereo installed.

Thanks

Hi. I'm finishing up the wiring for my AC-equipped 67 convertible, and I can't figure out where these two wire sets go. They are coming from the main wiring harness, but my NCRS wiring diagram for a 67 Corvette doesn't show them anywhere. I have no idea where to connect them. I would greatly appreciate any assistance in determining this. I gave the plugs #1 and #2 labels. Both of them have three connectors, one of which has four wires and the other has three wires. On the radio's left side, you'll find both of these. In anticipation of your assistance,
