I'd prob head back to SQ1 and work forward. Like with the VATS Bypass. Can you elaborate, like you spliced in the resistor, that matches the original Key Resistance Value iirc via the orange wire under the dash? What's the status of the Security Light? Do you have a GMSM where you can observe the proper troubleshooting tree?
