Any feedback from doing this kill switch yet?
Anything you like or dislike about it?
I did something very similar, only I found the single wire that led to all four injectors, so I didn't cut and splice all 4.
Mine kills and restarts very quickly.
If you want to get really fancy, replace the entire stick-shift knob with something like this...
The black switch now kills my fuel injectors, and the blue one will be for economy-boosting grappling-hook launchers.
