Kenwood DNX5120 with SWI-Jack connection HELP!!!!!!!!!!!!!!

Can anyone help me out here?
Please see the photo, I have a SWI-Jack with the DNX5120 and the wiring harness connection.
I have a problem to connect the SWI-Jack, I only know the red to key switch connection, and the black go to the ground, but how about the white wire? Also on the back of the SWI-Jack there is two wires hang out, one is a black wire, one is blue/yellow stripe wire, where do I connect the blue/yellow strip wire go to?
Please help me out? I really want to hook up the unit and test it out.................

 

the blue/yellow goes to the blue/yellow on the kenwood harness

 

How about the white wire ?????? ANy idea??

 

follow the instructions.

Steps #1 and #4 tell you what the white wire is for. Follow these word for word. It will take you a few times to get the programming down, so don't get frustrated.
