Does your method only work on the hemi ecu, or on all NGC and newer stuff? I've heard it doesn't work on SRT4 computers still, and I'd guess if that's true then probably same story for Jtec stuff.
Step 2: connect the alarm module to ground and power and to the pair of communication cables with pcm and finally just turn off the alarm and my swap turned on without problems
