I have a Red/Yellow wire on a blue plug that I am not sure where it went. The schematic shows a R/Y Wire for being part of the carburetor system, while I have the wire for the electric choke, the original carb doesn't have any additional electrical connections. The Vehicle doesn't have factory A/C so I am not sure what it is for or if it was even used.

Appreciate any feedback that you can provide.
