Competition Pro (I think) made a version of their joystick with an extra plug coloured grey with the Sinclair pinout.

The extra grey plug was for use with the +2/3 model spectrum's. Amstrad messed around with the pinouts of the joystick ports on the +2/3's to force consumers to use there own range of SJS joysticks with these models. Soon adapter leads came along, and third party joystick manufacturers added the extra grey plug.
