Well, he showed exactly how to perform the diag procedure to arrive at the wiring combination for the Ravelco device with his pulsing tester, the plug never needed to be at play. It makes sense and don't see how he would have cheated. He did mention several times that this requires a key, which, as we have learned elsewhere, takes a thief all of 30 seconds to program with an OBD-II device.

The idea here is that the tester uses short pulses to avoid triggering a fuse blowout. These testers likely didn't exist or were prohibitively expensive when the Ravelco was designed, and it may never have been updated to defend against them.
