    Okay, I pulled my Sirius radio setup out of my '05 AC before trading it in for a '10 DC. The unit is a SC-FM1 tuner.

    To power the FM modulator box and display, three wires (shown below) are spliced into existing wires coming from the stereo.



    Upon removing the unit from my old truck, I wrote down which of the stereo wires (by color and size) were used. However, in my new truck, the wiring is very different coming out of the 6-disc changer. I dont know which wires to tap into.

    The instructions say the following:

    (Yellow) = to vehicle battery +12V

    (Red) to switched ignition +12V

    (Black) = to ground -12V

    ?



    I think this is from the AUX input, could it be that these
    red, black, and yellow wires are indeed the ones I need?
    I dont know, as this stereo wiring certainly doesn't follow conventional wiring codes



    And I dont have any kind of voltage tester or DC light.

    ANYONE KNOW WHAT WIRES I NEED TO USE??
    ...and I cant find the specs for the radio anywhere

    any help would be greatly appreciated

    I got a Gen 1 and my cigerette lighters are switched. the ground you can pull off anywhere you can stick a spade under a chasis bolt... that just leaves you needing to find a 12V constant so you just have to find sumn that is on all the time or has a memory. Or take the guess work out and buy a 5 dollar bulb poker typer meter from radio shack and start poken around in your wire loom.

    Well, as for the brown ground wire, there are 2.
    each the exact same color, but different sizes. I dont know if either one could be used

    as for the constant 12v+ wire, I cannot find one in any cluster that's Blue/Yellow

    there is one very small gray wire though....hmm

    you should have two more plugs...one will have the power wires. 4 plugs total into the back of the radio. the two you show pictures off seem to be the wires to the speakers. You should have one plug for the steering wheel controls/aux input and another that carries the power.

    Edit....Or maybe you should have 3 harnesses total...i can't remember. But the harness only attaches by 2 harnesses, leaving one for the aux. I have 4 plugs on the back of my oem unit but i can't remember if they were all used.

    Ok...the white plug is the one you need to be using. the little wires in the corner carry the power it seems. The ground is the brown wire beside the purple wire, blue is your constant, and grey is your switched...like the man above said.

    wiring placement is shown here with a nice diagram.

    Yep, here are the other two plugs. There are four total.





    Not sure I understand you...

    Ok go back to the original 2 harness you had...you need to only use the larger one. you are looking for the little wires. Go to the link i posted and match up the pin configuration as to your wire color. From what i can see it should be.

    brown beside purple = ground
    blue = 12+ Constant
    Grey beside blue = 12+ switched

    I think ive got it.

    I have another kenwood head unit that I had in my old '05 truck. I still have the wiring harness with it that adapts to the plugs coming out of the dash. all the wires on the harness are labled and are the correct color. i can plug the harness into the dash and match the wires.

    idk if that makes sense, or if it needs to. I figured it out
