Just ran across this in a box of stuff.
I think I pulled it from a 5000 but can't remember.
I took it for the button which I hoped would work in my C4 (it doesn't)
Also took the trip computer because I needed a socket for a trip computer harness for something I was trying. So it has no way to plug the harness into the PCB.
Maybe you have a bad LCD and this will help
Anyway, should be a small for rate box $5
I know I'll never use it
