Hi there. I am Cam. Without knowing the resistor, your best bet is a VATS bypass by NEWROCKIES. This module installs inlace of the factory module and sends a constant bypass signal out to the ECM so it will run.
http://newrockies.com is the only place I know of, but they come with support, instructions and everything you should need.
This is the only way to truly bypass the VATS security system.
