Review on 🔌 Enhanced Wire Harness with 6 Volt Converter for Select Toyota and Scion Models - Retain OEM Factory Backup Reverse Camera to New Aftermarket Car Stereo Display/Navigation Radio - Check Compatible Vehicles Below by Joe Roberts

All these instructions are included in the package. This harness eliminates the need to search for +/- wires for camera signal and +/- for camera power. It even includes RCA jacks/plugs and a 12v to 6v buck adapter that is very easy to install (white to 12v in, black to ground and gray to 6v out, going to the feedback cable). 24 pin and I was able to find the return signal cable in the 28 pin connector on pin #2. But of course you need to figure out which wire to connect using the internet or a multimeter (the wire has the 0V but goes to 12V when you put the reverse gear in).
