I'm a n00b when it comes to ICE. I want to replace my Concert unit with a Pioneer DEH-4000UB. I have a PC9 - 404 wiring harness. I've connected it all up but am getting no power to the unit. Any help woulde be appreciated!
Don't hold me to this but I think the red and yellow wires need to be switched around.
Please wait for someone else to confirm this as i'm after forgetting since I done my one!!!!
I had this problem when i swapped mine to a kenwood dnx7220 multimedia unit, i had to get a permanent live put in by a local audio company and that sorted it out.

There are 2 ways to do this, you can either tap the red wire into the yellow wire, this will give you the permanent live needed to power up your head unit.
The downside to this is, you have to manually switch off your headunit everytime you leave your car.
The other option is to take a switched live feed from your fusebox to your headunit, this will switch your headunit off everytime your key is removed from the ignition.
If you do a search, there are several discussions regarding this.
Hope this helps.
Yes it will if both wires are connected up, the head unit has a permanent live feed going to it to retain any memory settings.
Have you connected the red plug? This feeds your rear speakers, the 2 phono plugs goes into the back of your head unit and the blue one if I remember correctly is the earth.
The blue cable on the aerial adapter is connected to nothing, is this important?
That's true, the rear amps are crap, wiring direct to the headunit is relatively easy, the only time consuming part is removing any trim to pass your speaker cables through.
It will sound much better than using the stock amp, while you're at it, why not change the rear speakers at the same time.
It shouldn't take anymore than a couple of hours to do at most.
Yes, that's correct.
Just make sure that you get the +/- (positive and negative) connections for the speaker cables the right way round.
I'm not sure where the original cables run from.
When you install the speaker cables, run the left speaker cable along the passenger side of the car, run the right speaker cables along the drivers side of the car, get the cables under the steering wheel (cable tie the cables in).
Take out the glovebox for the passenger side to make it easier for you.
No probs, you're welcome.
