If you buy the V2, it should come with the bed clips.
For a Taz 4, you will need to run the additional fan wires for the hexagon cooling fans if you haven’t already (the required always on barrel cooling fan, not the filliament cooling wires that were installed when you got your Taz 4)
Here is a good guide showing where the wire needs to go. https://ohai.lulzbot.com/project/taz4-hexagon-toolhead/accessories/
I’m assuming the V2 toolhead uses a Y splitter and splits off that 5 volt header to power both barrel cooling fans. It’s possible that there might be a second wire you will need to run that I don’t know about. Either way you should anticipate having to adjust some of your wireing harness to make this work.
