Red Lights out and it won't close the lid. Pulled it out. The brown/yellow wire is hot, the grey/yellow becomes hot if I depress the switch, but the blue/white still doesn't get power. I think there is a break in the hot wire at the plug to the switch, if I move it around sometimes the brown yellow wire looses power. But not being able to power the blue white wire when I depress the switch makes me think I also have a bad switch.
I think the blue/white activates the trunk closer. And the brown/yellow electrifies the switch generally plus the light? But what does the Grey/yellow do?
All the other trunk lid lights work, license plate lights etc
Maybe someone could point me to a color coded layout of the trunk please.

Best thing to do is go on EBay and get one of the boot leg WIS/ASRA DVD sets and install it on an old junker laptop (I'm using an old HP from 2010 that was my son's from middle school, slow but it works). Unfortunately the documentation for the 211 is not available online like the older models.

In the absence of data I would start looking at the wire pack where it flexes coming into the trunk lid. I suspect your broken wire will be there.

The trunk closer wires are on the left side of the trunk running along the left hinge. You can see them in a protective covering. You'll need to remove some of the cladding and get into the wires themselves and see which wires are parted. The trunk closing causes chafing and this chafing eventually causes one or more wire to fail. I've had the same issue and it's an simple fix taking a couple hours at most.

The goofy part to me is that there is no remote trunk closing; they should have put one inside the car or on the key fob.

I did find 3 broken wires, spliced them and alls well.
I did use the remote switch on the door while figuring out the fix
Thanks all for the tips.

I sold my Desert Silver CDI to my niece (trans went out on her 300CD, so she needed a car). I was originally looking for a blue one, but got a good deal on the Desert Silver one, so I bought it. I found a nice Platinum Blue one in Albuquerque. I got a one way plane ticket and the seller picked me up at the airport. We made a deal, and I drove it back to CA. I stopped at my favorite restaurant for dinner on the way home. This one has some minor issues, but nothing I can't handle. Overall, it is quite nice.....Rich
