Which adapter for 9 pin thru hull ducer to HDS Carbon

[Pepsi man]

I'm replacing an HDS live 9 with an HDS carbon 16. I need to find out which 9 to 7 pin adapter i need for the thru hull ducer. I'm not sure what brand or model the thru hull ducer is on my boat. Its a 2021 phoenix 721 pro xp. There are 2 adapters available, one for non chirp with analog temp and the other is noted for airmar transducers. I contacted my boat dealer but my dude is in vacation and I have everything I need for the install minus the adapter...any help would be greatly appreciated...
