Connections to the rear of the unit. RCA connectors are for output to amp(if fitted).
Main connector:
Yellow - To be connected to supply that is always "hot" irrespective of ignition position. This is for memory backup. If you cant find the original wire on the car it is recommended that you fit a new one straight from the battery. Be sure to use an inline fuse(15A) as close to the battery as possible. On the harness leading to ignition will be a thick white wire which will ne "always hot". It can be safely wired to this point as well
Red - To be connected to power from ignition. This line should power up and down with ignition operation. Red and yellow can be connected together and then to an "always hot" line. You will be able to use the radio with the ignition off, but forget the radio on and you have a flat battery the next morning.
Black - To earting point or negative of battery.
Blue - To auto antenna relay and/or amp power control. Do not connect directly to auto antenna. Always use a relay. Have a look at the following link if you're not sure about relay wiring :
Yellow/black - Equipment using an auto mute function ie handsfree cellphone kit is wired here.
Speaker connections:
White - Front left positive
White/Black - Front left negative
Gray - Front right positive
Gray/black - Front right negative
Green - Rear left positive
Green/black - Rear left negative
Violet - Rear right positive
Violetblack - Rear right negative

    On the CD changer connect the black connector of the bus cable to the CD and the blue connector to the head unit(radio). The small black wire can be connected to the vehicle bodywork. The yellow can be fed to the radio and connected on the same line as the radio's yellow. Always set the angle switch so that the slot is horizontal.

Pioneer radio wont retain station memory

clock probably doesn't stay either.....sounds likke the wiring may be incorrect...there are 2 battery + leads on these radios...One is yellow...which should be hooked up to a hot lead that is hot all the time even with the key off( you could just run a wire to the positive side of the battery)..thios lead is the memory lead that keeps stations, settings, and the clock....then there is the red lead that is supposed to be hooked up to a switched positive lead...such as the accessory lead fron the ignition's a good bet that the red and yellow leads are hooked together and that they are hooked to a switched ignition lead right now...all you have to do is disconnect the yellow lead from where is hooked now and hook it to a hot all the time then your memory, and stations should be retained

I need wiring color coding 4 pioneer deh 2050mpg? i know red is constant power.

Not to question you about the red being constant power but I have a pioneer deh-1600 car stereo and red is hooked to electric terminal controlled by ignition switch (on/off) and if your unit has a yellow wire that goes to constant power. The only problem with hooking up the red wire to constant would be if you happened to accidentally leave your player on it could drain the battery. Hope this helped a little. Good luck.

Lost memory

Car stereos typically have an "ignition" and a "battery" wire. The ignition wire is connected to your ignition switch, and only supplies power to the stereo when the car is turned on. The battery wire is connected directly to the battery, and always supplies electricity to the stereo -- even when the car is off. This maintains presets, clock, and other settings in your stereo.

It sounds like your battery wire was either not hooked up, or has come loose. On your stereo, a Pioneer, this wire is yellow. Locate the yellow wire on the wiring harness on the back of your stereo. This wire should be connected directly to your battery (or another source that gets constant +12VDC).

Need a hot wire radio switched

The black wire is the chassis ground and should be hooked to an unpainted metal surface. The yellow wire should be hooked to a constant 12 volt line, one that is not controlled by the ignition switch.

You can find more installation information in the online installation manual.
