It looks like the frame holes (SSEVO) are 'just' wide enough to allow a connectamajig through, so I'll try leaving them on and plugging back in if reusing them wont result in fiery death.
If you're moving an internally routed handlebar to another frame I'd disconnect the calipers, if you using a new bar, or externally routed unplug the shifters.
Hot tips thanks @amey @chiroshi
