Did the wire look like the one in this picture?

How to bypass the VATS system in a late model GM vehicle
You should have followed the wire to the junction box Tec II mentioned, if you remove the cover/panel above that you should see the block with all the wires running into it, the end of the orange wire should look like you see in the pic.
Is there any way you can get a pic of the wires you cut?
If you can get to the power junction block, and unplug the plug with the orange wires, you could solder the resistor pack you make into the connector, then plug it back into the junction block.
