i strippled the bike down to powdercoat the frame, now im building it back up i found a plug with no label, it must have come off,

any ideas what it is for?

thanks

Wire colours are always more helpful than picture of the plug.
I suspect it is the CA-Only Purge Valve connector (Yellow/Red and Brown/Pink wires) - would not be used on your bike.
