Single Extruder Tool Head v2 and TAZ 3.1

I have a Lulzbot TAZ 3.1, though I am planning to print and purchase the parts to upgrade my printer with TAZ 4 parts. I saw that Lulzbot is advertizing the “LulzBot TAZ Single Extruder Tool Head v2”, but only specifies installation on TAZ 4 printers. While I am sure one could make the new tool head fit on any TAZ version printer, I am wondering what modifications(if any are necessary) are needed to make the new tool head work with the TAZ 3.1.

I saw a link to the Lulzbot Facebook page from my searches, where Lulzbot claims the v2 tool head is an upgrade for the TAZ 1-4(https://www.facebook.com/LulzBot/posts/851143804944912), but no specifics on how much work and what alterations(if any) would be needed. On the TAZ 3.1 part, I see two connectors, though I want to say the video I watched on the tool head installation mentioned four connectors. Would the walkthrough on the Fangtooth Tool Head(https://ohai-kit.alephobjects.com/project/taz3-hexagon-toolhead/) give some idea of the installation work necessary?

My apologies if there has already been a post on this topic. I didn’t find it through the search function on this forum, nor through three different search engines.
