vacume hub system

I will be buying manual hubs to fit to my 2001 non abs jimny, thus making the old vacuum hub system redundant, so i have read about flashing lights on dashboards etc. so my question is what parts of the system can be removed to get it out the way

cheers

I removed as much of the pipework as possible then put 2 self tapping screws into the ends of the pipes that come down from the engine bay = no flashing 4WD light !!
