OEM 6-disc CD changer install

This part is pretty simple if you follow the wiring diagrams and CDX wiring chart that is included. First of all make sure you have the correct CDX. A 2001-2002 CDX will NOT work!! You need a 2003 or later CDX that speaks on the Class II data bus. The only visual difference between the two is that the 2002 and older units had plastic slides on the sides for mounting. The 2003 and up units have metal tabs, or “ears” sticking out of the sides. Now remove the black plastic console bezel that holds the two cig lighters/12 volt outlets. It just pulls out. Give it a good yank. Look in there and you will see a perfect space for the CDX…except a big lump with a hole in it is in the way. Simply cut it out. I Dremmel’d it and finished it off with a mini-hack saw and finally, just grabbed it with a big pair of Channel-locks and broke it out. Just be careful cause there are some wires RIGHT behind it. Snake the CDX harness from the radio area down to the console. Then plug in the CDX and bolt it in place with some self tapping screws. To fit the plastic bezel around it, I cranked up the table saw blade as high as it would go and just cut off the “back” of the pocket on the bezel. Don’t cut if off completely. Leave about 3/16 of an inch to fit flush against the CDX’s own bezel. You’ll figure it out once you start. Keep trimming it back until it fits perfectly. Now just follow the wiring diagram in the picture to splice in the wires at the correct places on the two radio connectors. I soldered them, but you can use ScotchLoc connectors also. If you DON’T have XM, there wont be any audio wires on the radio C2 connector to splice into. In that case, just remove the pins from the 9-pin flat CDX harness plug and insert the pins into the appropriate places on the radio C2 connector. The pins are the same size on both connectors so they will plug right in. If you have XM, splice the wires in as normal.  

RADIO C2 CONNECTOR.....................CDX CONNECTOR
Pin "H"--------------------------------> Pin "10"
Pin "J"---------------------------------> Pin "11"
Pin "K"---------------------------------> Pin "12"
.................................................. .......Pin "8"--------> not used
.................................................. .......Pin "13"-------> any ground
.................................................. .......Pin "14"-------> any Class II data source
.................................................. .......Pin "15"------> any fused 12 volt power source


All other pins in the Radio C2 connector are not used except for "E" which is the VSS wire. If you have OnStar, "L" and "M" of the Radio C2 connector will have orange/black and pink/black wires in them, respectively. If you have XM, Pins H, J, K of the Radio C2 connector will already have wires in them. DONT CUT THEM! Strip the insulation back and splice into them with the correct CDX wires. I like to solder the wires in, but if you are not comfortable soldering, Scotchloc wire taps/splice connectors work fine.
