Wiring kit with various wire connectors, ideal for transplanting and installing genuine Toyota and Daihatsu car navigation systems and audio systems. *Also includes a 5-pin sensor connector for navigation transplant patterns. (Another 5-pin connector is included so that the number of pins can be processed) ★The terminal diagram is the arrangement viewed from the back with the lines. ★5-pin sensor connector arrangement (Blue wire: Parking wire) (Red wire: Reverse wire) (Pink wire: Vehicle speed wire) There is no reverse wire at the end T, so please remove it from the other one and add it if necessary. ★Please be careful not to make a mistake as it is a Toyota and Daihatsu audio connector shape. ★The main male coupler has two wires each for constant power, accessory, and illumination, making it convenient for separate power extraction. The ground wire is extended. ★This is a male coupler harness for installing genuine Toyota and Daihatsu car navigation systems and audio equipment in other manufacturer vehicles like aftermarket products. You can use it like an aftermarket product by plugging it into the connector terminals on the back of the unit. Please install it like an aftermarket product with a separate car model-specific audio installation harness connected. - Wiring type: Multiple wire connectors - Number of connectors: 4 connectors, including the main harness, rear speaker harness, and 2 x 5-pin sensor connectors for navigation - Wiring: Power, illumination, speakers, antenna, ground - Terminal type: Crimp terminals When aftermarket products are expensive and difficult to obtain, You can install relatively inexpensive genuine products, and the genuine quality will look natural and smart. I think it can also be used for large navigation systems such as Toyota. You might want to try using a used large navigation system with a modified version. Thank you for your consideration.
