If your RB5 or RE2 radio already has the C3 connector with populated wires like the photo below, you will not be able to use our connector because you will lose audio and microphone for bluetooth functions.
You will need to do a re-pinning procedure to add Camera Signal and Camera Return to your factory connector.
The connector provided will have to be de-pinned and repined to the factory connector circled in yellow above. The two pins, 15 for Camera Signal and 16 for Camera Return will not be on the factory connector, they will be vacant. Once the two wires are depined from our connector, they can easily be inserted into the factory connector. Please use the pictures below for reference. Mating side is what touches the radio, the wire insertion side is where you'll be pushing them into on the factory connector.
The RED wire will pin to 15, and the BLACK wire will pin to 16.
