I managed to get the seat out, along with the immobilizer. Really wasn't that difficult with the right tools.Unfortunately, the immobilizer itself looks toasted. The circuit board near the black 12 pin socket was charred and the copper foil bubbling up. I will need to send it in to
Specialized ECU Repair. They will also need the ECU itself, which I think is in the rear trunk. But since I have the immobilizer out, I need to find a way to manually pop that rear trunk so I can get at it. That will be quite a trick without any power.
