2007 audi a3 vss, illum, acc

Okay, I think I have everything I need for the install.

Only wires going into the HU are +, -, and bose (which I've read has nothing to do w/ an aftermarket HU and will not be used).

Also the FL, FR, RL, RR, COM, and 12+ switch were all connected.

So, it looks like I need:

as it has a hookup to the FL, FR, RL, RR, etc...to RCA's that will connect to the D3's RCA output, and has another connector for 12+ and ground (-).

So it looks like that is what I need (already have antenna adapter, and know what fascia I need). Only question now, is where to find 12+ switched (ACC), illumination (could do without) and VSS.

From what I've read, I can tap into the homelink fuse in the driver side kickpanel (not 100% sure) for the 12+ switched (ACC). I haven't found much on where to find the VSS, other then possibly the cruise control box behind the glove box (was on a onder model though).  Any ideas/pictures on the easiest  place to find these 3 wires?

Sorry for the messed up pics. Here they all are:
