Why use a genuine Sony headunit harness? The aftermarket harnesses are often poorly made and sometimes the power/ground wires short or cut out as they don't sit in the plug properly due to cheap manufacturing of the plastics. The genuine Sony harness is quality made, and also has all the pins in the correct place!

This GENUINE SONY harness is also suited for other SONY branded headunits including the following:

And many more SONY audio visual models with the smaller of the 16 pin harness. If your model is not listed above then please message me to confirm if it is suitable for your headunit.
