Help please!

Searched and searched and gettling a little confused with what wiring I need.

I'm looking at thwe following 3 items
Fascia and cage http://caraudiosecurity.com/shop/pro...s_id/6867.html
Interface:

Patch cable:

Basically, I am fitting my double din pioneer unit and need to know if any other wiring is required. Does the interface cable connect the existing stereo wiring to the standard ISO or is another cable required?

Thanks in advance
