I actually just finished purchasing all of these pieces and let me tell you...it's not as cheap as you would think.
First off, here are the correct part numbers...
Connection Housing to DV: 1J0 973 722 A
Connection Housing to Harness: 1J0 973 822 A
000 979 133 A: Wire (x2)
000 979 134 A: Wire (x2)
With my discount at my local dealer...all of the pieces cost me just over $40 (I believe you can get them for roughly $32 + shipping from 1stvwparts.com, but shipping may cancel out any savings).
Note: I initially purchased those same parts numbers you listed above (probably from the same thread you got the information), but they were not correct and did not attach to the DV housing plug. From there, I used ETKA (thanks to Duke) to find the correct pieces...which are listed above.
Note (2): I might have mine for sale here within a week or so...might not end up taking the planned path of relocating the OEM DV and just stick with the Forge SS Valve. If you're interested, LMK and I can keep you up to date on my decision.
