Charger wire queation

Alright. Project gem is almost complete. I’m in the process of putting it back together.

My old zivan charger is shot so I replaced it with a new delta Q.

My question is I was under the understanding that the green and red wire on top of the zivan charger is the interlock and that there is no way to make it work with my new charger since it only has 1 green wire coming off of it. I was told to just connect the green and red wire together to bypass interlock. Well I’ve got everything almost back together and the gem runs with the 2 wire unhooked. I hook them together and it doesn’t change anything?
Any ideas what’s going on there?
