Motor connectors

[Link]

Hi, i needed to remove the bash guard to check the motor bolts for tightness due to creaking noise, anyway, as i did that i noticed that the empty connector on the motor for the 12v supply or rear light (which i don't have) is lacking a rubber grommet cover, so its already got some mud in it Not really an issue as i don't have lights connected, however i would have expected it to have a cover. Anyone else noticed one missing ?
