You are purchasing a New Auxiliary Input / Output harness for a Rosen and Carshow drop down overhead TV/DVD system. 

The Rosen part number is an AP1038.  

It is compatible with Z8 and Z10 models.  

The harness plugs into the 6 pin input or output plug in the top of the unit and provides an additional auxiliary audio/video input or an a/v output to other devices.  Please note that if you need an input and output then you will need two harnesses.

Please feel free to contact me anytime with any questions.  Thanks for your interest!
