Another C5 stereo question.....

I went to Car-toys the other day to discuss installing my Kenwood head unit (just a standard single-din cd player). They stated that in order for me to keep all of the Bose speakers functioning, the "special" wiring harness was 129 bucks....I immediatley started laughing and walked out. I have been searching for the correct wiring harness and I think I have finally found what I am looking for.... http://cca.madvettemotorsports.com/s...ct_detail&p=68
This is the SVEN2 & smart harness (SVHGM4) for $55. All I want to do is replace my head unit and keep all of the Bose speakers operating as they should. Will this work for my application or is there something else I should look into?
Sorry if this has been repeated 1000 times here, there is so much info to sift through and not enough time on my end to search....Thanks for your input guy!!
