  • Cdesolator Feb 13, 2009

    ok done that, so in my car the red wire is is always on and the red/brown wire is ACC.

    but on my radio I have the always On wire on the place were the acc wire must be and the acc wire were the always on wire should be. do I need a new adaptor for my radio or do I need to rewire the radio wires in my car ?

Hi and welcome to FixYa,

Let's start with the basics:

  • yellow wire to an always on B+12;
  • red to ACC terminal of IGN switch;
  • black to ground;
The yellow/always on is responsible for keeping the memory, that is the stations that you have had memorized/selected. The always on is directly connected to the battery's + terminal.

Would appreciate any updates. Good luck and thank you for using FixYa.

    The best check then would be with the use of a DVM/VOM (voltmeter) or preferably a test light. The always on wire must measure/read 12VDC with or with the key in the IGN switch turned. On the otherhand, the ACC wire would only have +12 when the key is turned either in ACC or RUN/ON.

    Simplest would be to switch them, no adaptors needed. The car's red wire should go to the yellow of the Pioneer and the red/brown wire which is ACC should go to the red of the Pioneer.

generally wiring from the car is as follows...

red = ignition controlled live
yellow = permanent live

if you want stations saved and manual switch off of uni connect radio's yelow and red wires to the cars yellow.

if you want stations saved and radiounit switch off controlled by ignition (i.e only when car is running) then yellow to yellow and red to red. anything else will cause issues...

Fitted clarion db148r car sterreo(pluged in at rear) when i take ignition key out stereo switches off and all preset radio stations are lost thanks george


The reason you are loosing all of your presets, clock & eq settings is because the 12volt constant is not hooked up properly. The red wire in the harness needs to be hooked up to 12 volt consant. The yellow wire needs to be hooked up to a ignition source. By taking these two steps, you should have normal operation and preset retention.

Memory not working


check the yellow wire is the main power so always need to exist power on that wire even if the key is not on the ignition switch,and the red wire need to be conected to a switched ignition wire from the vehicle.

Radio Station Presets wont hold


hi girlygirl 1

the problem is your ignition and your permanant battery live wires are the wrong way round all you have to do is remove the stereo and you will usually see a red wire plug into another red wire and a yellow wire into another yellow wire all you have to do is change the red to the yellow and the yellow to the red and it will hold the memories fine hope that helps !

DehP6700 mp restet everytime keys is turned on.


first red is ignition or acc (turns off and on with the key) yellow is constant power (always hot keeps memory) orange is illumination (lights up radio) if vehicle doesnt have a seperate illumination wire connect it to the ignition wire. now process of elimination your ground is correct because it worked with all wires to acc your acc works because u had all them connected to it and it worked your problem is in your yellow or constant/memory i suggest u test it again take piece of wire any old thing long enough will do and run the wire directly from the battery under the hood and just run it outside the car through the window and connect it directly to the yellow wire make sure u have a good connection at the battery on the positive side if u have test light or volt meter test the wire before connecting it to the radio if it works then u know there is a problem with the wire from the vehicle (fuse wrong wire bad wire ) if it doesnt work make sure ground is connected tight and that paint is cleaned of the surface where ground connects and that the yellow wire to the radio is tight in the back of the radio.

Kenwood kdc 3011 rests its self every time i turn the car off


This means that the power lead you connected the red and yellow to is a switched live and each time you turn off the ignition the power goes off and therefore resets. to fix this problem you need to connect the yellow to a permanent 12v supply that stays live when you turn off the ignition.

Resets when car ignition is turned on.


you will need the code unfortunately, you can patch in a pp3 9volt battery but it is akward.
i suggest you go back to the garage and let them have a go swapping the wires round

Memory loss


you need to remove the radio and swap the red wire for the yellow wire and vice versa, they have bullet connectors to allow you to do this, basically the permanent live and the ignition live are the wrong way round.

Tuning the radio


You have two "hot" wires going to the radio. One is the main B+ power and the other is for the "mem" function which keeps clock time and radio station presets in memory. Make sure that you have 12 volts to the memory wire (blown fuse?) If you do then you may have a problem that requires a trip to your local repair guy. Do you loose your preset stations when you turn off your car and leave the face in place (wait several minutes before turning car ignition back on)? If that is so, then you most likley don't have B+ to your memory wire. Good luck.
