Suitable for use with Mazda CX5 (2011-2015) and CX9 (2011-2015) vehicles, the APVMZ02 Reverse Camera Retention Harness enables the OEM reverse camera to be retained when installing an aftermarket AV headunit into the vehicle. The harness includes a vehicle specific plug which connects to the factory reverse camera loom and provides an RCA plug which connects to the reverse camera input on the aftermarket headunit. The harness only requires a small amount of wiring, a black wire with ring terminal that needs to be connected to ground and a violet/white cable that needs to connect to the reverse trigger (12V), making it simple to install.
