Dark greys appear a dull green.

Does the two plugs fit together? Wiring color will not match as aftermarket speaker wire use light grey, dark grey, green, and purple where factory wire uses blue, green, dark blue, and tan

no you need to adjust the color wheel to factory specs by getting into the service software. The color wheel has to be timed to the engine.

Brian, first of all, make sure you have a multimeter and let's agree on one thing: any wire that has a switched voltage or a voltage to control antenna or motor has to be DC type of voltage, right? The other ones for the speakers are AC voltages as in music, right? Therefore, I would go with a meter between the wire and ground and measure on the DC scale and turn the radio on. Keep an eye on the meter and you will see that if the voltage appears, it is a DC voltage and it will answer your question. Hope it helps.

You probhably have the wrong color wheel. There are several different ones and its imparitive that you replace it with the correct one. If you search here theres someone else that had the same issue and when they put thier old noisy color wheel back in the problem went away.

This is a fundamental limit of Ti DLP. The part can not reproduce low grey scale, so low light film is dominated by artifacts. It helps to sit farther away from the screen. The color shift is caused by a factory tollerance on the color wheel, but there is no user adjustment for it.

With the back off of the unit, you are looking at a silver can on the light engine. The is the board where the DLP IC is located. There is a large heat sink right in the middle. Near that heat sink you will find a small square cut out where two pins protrude from the inner bd. There is a small black piece across those two pins, that is the jumper. With a needle nose slide that black jumper off of the two pins. Normally if the color wheel is changed and the jumper not remove the picture is very poor with ugly green and purple negative look.

Notice, this is from the 2005 Ford F150 Wiring Harness. Other radios should be the same or very close. From the main 24 wire connector on back of radio (C290A).
