Hey Guys - I have a new to me pair of Mercury V8 300 CMS DTS (3B216004) motors that I'm gathering all the components to get rigged and running into a roadblock

I currently have these parts and harnesses:
892451T25
87-893353T04 Mercury - Key switch-dual - 87-893353T04
84-8M0157213 Mercury - Helm Harness - 84-8M0157213
84-899785K30 Relay Harness Kit
8M0133240 Gen2 DTS Control

I am stuck on the clean power harness. I can see in the installation manual it talks about the 2 pin harness which as far as I can tell is 8M0113732. but then I also see Mercury Next Gen Clean Power Adapter & Harness # 8M0187441 & 8M0158087. Would these be used together or is the second set of parts not applicable? The battery is near the motor. I am looking to get everything I need together while I wait for the dealer to fit me in.

Any guidance would be appreciated!
Thanks!
