Gearbox drain plug seized 200

You'll want to do more than unplug the ECU. If you weld to the transmission drain plug, the grounding electrode must be adjacent to the broken drain plug being welded. If this isn't done, the electric current can flow through ball and roller bearings as well as bushings. They'll be toast if that happens.

With the welding ground in the right place, I wouldn't bother to unplug the ECU and EZK, but it can't hurt.
