That diagram PRESUMES that you have regular RCA type AUX in on your stereo (option 2). The Civic HU doesn´t.
Therefore you need the connects2 to do that.
It will sit between the Black Box and the HU.

Option 2 is the way you want to go for good sound quality. Option 1 may work in the Civic but as I understand it that converts DAB to FM. = loss in quality.
