To add this functionality, you would need to source the parts individually and potentially do some wiring yourself. This would involve:
* A button: You'd need to find a suitable push-button switch. The size and style will depend on where you want to install it.
* Wiring harness: You'll need to wire the button to the existing trunk release mechanism's circuit. This requires finding the correct wire in the vehicle's wiring harness. This is the most challenging part and requires some electrical knowledge. Getting this wrong could damage your car's electrical system.
* Relays (possibly): Depending on the amperage draw of the trunk release solenoid, you might need a relay to control the circuit safely.
* Installation location: You'll have to decide where to mount the button and drill a hole (if necessary) to install it.
Unless you're comfortable with automotive electrical work, this is a project best left to a professional car audio installer or mechanic. The difficulty lies not in finding the parts, but in correctly identifying and tapping into the existing wiring harness for the trunk release. Improper wiring could lead to blown fuses, short circuits, or even damage to the car's computer system.
