Harness Question before Plasma Cutting
 

I'm about to plasma cut out the interior of our suicide doors and I removed the door harness. My question is what body harnesses can I remove in these modern cars without affecting the drivability of them? If it thinks the door is ajar is going to limit my speeds to 20mph or anything weird? Its a race car so only need the engine and lights to work. Maybe the blower and wipers.
