Ace Pro Kobra 3 Combo use on Kobra S1

My friend gifted me his ace pro he had for his Kobra 3 v2 and I currently have a Kobra s1. On the website when ordering you need to select which version to buy. Is there any difference between the ace pro models and can I use the one that came with the Kobra 3 with my Kobra s1?

Some background I have a Kobra s1 combo kit so I already have an ace pro attached to that. I assume all I’d need is the 8-color hub and use the 4 tubes he gave me as well as the connector cable to connect to the existing ace pro.
