A friend stripped a VTS for use of the engine etc for a 16V conversion.
Unfortunately he unplugged the wrong black box with the engine running to unlock the ECU, see box:

He then tried to unplug the coil by the ignition to see if it had worked, it snapped it as below. After this, it started fine for a second then he turned it off.

Does this mean it has work and it is unlocked, or will it have cut out after 5 seconds etc?
