This is a coupler needed when installing aftermarket parts on Mitsubishi cars. They are surprisingly expensive when purchased new. I am selling items that seem to be perfectly usable even as used goods, so I think you can use them with confidence. If you want multiple items, I can accommodate you, so please feel free to contact me. Navigation Audio Coupler *Used item* If an electro tap was originally attached, I remove it before listing the item, so there may be exposed wiring where the vinyl has been stripped. We recommend repairing it with vinyl tape or the like before use. We do not ship on weekends and holidays. *Since we ship by regular mail, there is no tracking number and it will take some time for the product to arrive.*
