Ok, as promised here are some photos of the viu module that I removed from the DTS' trunk. The part number is Delphi 12201539. If you have this unit, my module should work for you, since this is what my module is emulating. The harness is GM part number 12450687. If you have this, then my kit is plug and play. This harness has three connectors on one side (red and blue connectors plug into VIU, and DB25 connector plugs into cell unit.) The other side has the same connector as my harness. So you need to remove the viu/cell combo and the harness that goes with it. (Actually, you could just remove the harness and eave the viu/cell module, but then you have to find another place to mount my kit.
I also have a manual which shows the pinouts and a little more info on how to use the kit. It's a modified version of the moto manual.
***Note*** This is not ready for prime time yet until you guys have tested it in various vehicles. As i mentioned before, I did this for my vehicle only and have not tested it anything else. Once you guys are happy with it, I can make it available to all. CoSTAR technologies will be the company name and the product will be called the BlueSTAR. but IT IS NOT AVAILABE TO THE GENERAL PUBLIC YET!!!
