Pioneer DEH-P3000IB wiring question

http://servicerepairmanuals.net/hifi/pioneer-deh-1400-high-power-cd-player-service-manual/

go to store that sells car decks and look for a wiring harness for ur car its about $7 mybe and prettymuch match the colors on ur deck to the harness and then pull ur old deck out and pull the harness from the back the back of that deck and plug that into the wire harness u just bought and hook up the antenna for radio andput the deck into the dash the wire harness should also come with so directions too just in case

This is not as straightforward as you may think.

You can certainly buy a generic adapter harness which will plug into the European DIN harness and then provide you with the bare wire tails to patch into. You may even find one which plugs directly into the rear of your head unit without the need for patching.

But you'll find that your head unit still won't work properly as the US uses a different FM channel range to Europe (US frequencies are odd, e.g.102.7, Euro frequencies are even e.g.102.8). The channel spacing is also different.

The radio itself cannot be converted, but you may be able to buy an external converter. It won't be cheap, and the head unit display will still always show the wrong frequencies. Channel changing may have to be done directly on the adapter and not on the head unit as I don't think that the DEH-P3000 has any way to communicate a request for a channel change to any external device and this also means that radio channel presetting may be impractical/impossible.

Considering that the DEH-P3000 is an obsolete unit and nothing special to begin with you can buy a brand new Euro-spec head unit of equivalent quality for less than the cost of adapting your unit and it will work correctly without any awkward Heath Robinson adaptations.

Sell your Pioneer back to the USA where it belongs or bin it as it's useless over here.

try looking at the gray, white and green wires and see which position the wires with the black stripe are. you should be able to get a good idea which should be the purple/black from that.

You can usually purchase a wiring harness for your vehicle to ease the connection to factory wiring. Two examples would be here:
Toyota Into Car Harness
Toyota Into Radio Harness

Just press the bottom ipod in your player and start browse your ipod lists from your player

Quickly piush and release the source button if you hold it down to long the radio will turn off

make sure you have the yellow fuse wire hooked up to bat. power (always hot) red wire is your ignition power

The constant power (yellow wire) needs to be connected to an unswitched +12V source. It sounds like that's either unconnected or you've connected it to a switched power source.
