This is a coupler needed when installing aftermarket parts on Toyota and Daihatsu vehicles. They are surprisingly expensive when purchased new. I am selling items that seem perfectly usable even as used goods, so I think you can use them with confidence. If you would like to purchase multiple items, please feel free to contact me. Navigation Audio Coupler *Used item* If an electro tap was originally attached, it has been removed before listing. Therefore, there may be exposed wiring where the vinyl has been stripped. We recommend repairing it with vinyl tape or the like before use. *Shipped via non-standard mail, so there is no tracking number and it will take some time for the product to arrive.* (Delivery is only available on weekdays)
