Hey Fontyyy.

Lizard's right. If it needs the red thingy then swap it over. If it doesn't then don't.

You could of course paint your stock one red and pretend it's HRC.

That little black pot is quite important. Unless you don't want it, in which case you can take it off.....probably.

Oh, and if it looks like the pictures then it's probably right. Unless Andy drew the pictures of course!
