Winner International is the same company that owns The Club auto theft prevention device. It's likely if you write to the m they could tell you how the device was installed. It really shouldn't be that difficult though. Chances are there is a wire from the distributer or the batter going to the "Winner" device and then to your ignition. Removal should be as simple as removing the device and seeing where the empty space is on the back of your ignition switch. If you don't want to do any of that yourself a car stereo shop would be my recommendation to have it removed. The concept on 99% of the antitheft devices is the same and they should be familiar with how to remove it. Finding a shop that has been in business for a long time might be helpful also. Someone there may have actual experience with that device.
