FOUND THIS UNDER MY DASH WHEN I INSTALLED NEW SPEAKERS. PRETTY SURE DASH HAD NEVER BEEN OFF BEFORE.

ALSO SAW SIMULAR ONE ON A DASH IN THE J YARD.

RPO listed: A31 L03 C49 A90

I think that was a tag used for the person installing interior components. I'm pretty sure the car doesn't get its RPO label untill after the car is all done, so they use these "build sheets" to tell installers down the line what options to install.

So looking at your tag, they installer knew to put in electric window switches, a cluster w/ V8 Tach, Rear defroster button and a rear hatch release button.

It's the assembly line test report for the instrument panel wiring.

Interesting, you can learn something everyday with these cars. I found my RPO in the rear "glove" box in MINT condition. I don't think that box has ever been used. When I get the car back from the dealer I plan to take a picture of it and run the codes.
