Bypassing Neutral Safety Switch

How exactly would I do this? I'm not good at electronics so I really need something specific and idiot proof. This is just a temporary solution while I'm painting my car so I can move it around easily (ie be able to actually start it without crawling under it). My interior is complete ripped out so if there is a way to do it inside the car that would be preferred as it would be easier to undo. I'm eventually swapping in a new drivetrain with a 5-speed so that is the reason I don't want to screw with replacing it when it will soon be eliminated altogether.

TIA

Anyone?
