Thanks for posting these parts. Everything worked perfectly for me too.
Also wanted to add the parts link for anyone looking for the male connector that will seal off the speaker itself:
https://www.mouser.com/ProductDetail/571-1-1718643-1 This looks to be the same part that comes with the Abstract Ocean kit. I also bought two cavity plugs to seal it off too.
As stated above, definitely skip the cavity plugs for the female connector that attaches to the wiring harness.
Don't forget to order at least
two of the wire receptacles (1718760-2). Or extras in case you screw up the crimping.
