The thing about these cars is that the wiring harness is custom made for each car. Since yours didn't come with the H/K system, it won't have the extra wiring you need. There is a thread here or at Fanatics about retrofitting the H/K system to a non-h/k car. It will have all the answers you need... just search for it or there may be a direct link in the WIKI.
True story... I didn't order my car with premium pkg so it did not come with an auto-dim rear view mirror. I purchased a used one and had to wire in switched 12v and ground to the connector so it would work. A foot of wiring and 2 contacts... no, you may not have that if you didn't order the $700 option pkg!
