I'll answer your PMs publicly so that others mat benifit from the information and discussion. First, link to another topic which contain some information:
In your PMs you confirmed (sort of) that you removed the original VATS wires and replaced them with those from a loaner ignition switch. It'* important that the originals were removed otherwise the two resistances would be in parallel, thus dividing the key resistance in half (providing that they are equal).
You also asked where a resistor could/should be soldered in to bypass. Typically it is at the easiest location to get at with a soldering iron. With the information you've provided so far though, it seems that you have the car somewhat apart. In this case, I'd solder the appropriate resistor value directly to the "regular" wires. The ones that run from the back of the main ignition harness to the VATS module. They are WHI and PUR/WHI if I'm not mistaken. Actually, for better troubleshooting, use some alligator clips and temporarily make a good connection with the correct resistor value to those wires.
