I installed a kill switch primarily so I could EOC at night (the key switch turns the headlights off). My kill switch is a toggle that disconnects the (single) injector ground, so if I'm on a long downhill, I can leave it turned off, and still have engine braking & vacuum. My car doesn't DFCO below about 45mph.
I'm about to pull the power steering pump, so the lack of power steering is no problem
