What exactly is your problem?
I had problems with mine as well. The instructions called for a pink wire where I had a brown one. I had to reprogram it a couple of time to get the settings to take. The website for the PAC SWI-RC has good instructions if you input your model, year, etc. They have good customer service and the guy on the phone talked me through a few things. If I had a do-over I would get the Metra Axxess steering wheel control instead as it self programs. Otherwise I love my Kenwood setup.
There are a few threads on this site that may help if you use the search feature.
Here is one...
