If your supply is cut for a couple of seconds, then you will need quite a large capacitor to keep power supplied to the head unit, especially if the volume is turned up quite high at the time. You will also need to think about the choice of diode that will be able to cope with the current demands of the head unit and also the inrush current of initially ...

Solar Mike's answer is correct in it's description, however I would also add the following from experience. When I have done this in the past (20-odd years ago I think!) the harness adaptor came wired with the correct colours and pin layout according to the ISO specification and the majority of cars but if I remember correctly the permanent and switched (ACC)...

I checked this out in a 2012 Colt. There was the same connector but only with 3 pins connected. Green, purple and pink. I found out The Sony XAV head units have integrated steeringwheel control for japanese cars. I conencted green and purple to tip and ground and it started working directly. I measured the old radio what was happening on the pink cable, ...
