For those with trunk mounted batteries and drag race you probably know an external kill switch is mandatory.
I was at the track last weekend and the track tech called me on it for not having a kill switch. A Ford tech was there and he came over and offered a very good suggestion. As most of you know we have that fuel cut-off switch in our trunks on the driver side. He showed me the 2 wires that control that switch and he said to wire in a "NORMALLY CLOSED SWITCH" and just mount the switch on the outside rear of the car somewhere. If for whatever reason the car has to be killed just open the switch and the car will shutoff within seconds (due to the fuel supply being cut).
