I don't know about the resistor trick, i just cut the passlock wire and put a switch in. I've even unplugged my battery for a few hours, and switched the switch to enable it. turned the car on, and then disabled while the car is running. It's easy to do, skill level 1 i'd say. You just need wire strippers (a knife could do it) and a switch from radio shack. I soldered long wires to the switch and then just wire knoted it to the other ends of the security wire. I'm sure you could do it with out soldering, just loop the wire in the hole that comes on the switch.
