So far I have seen 2 types of killswitch for the insight 1st gen. The FAS system from M Dabrowski, which keep the dc/dc running while EOC, BUT, When you put it in gear it restarts automaticly with the IMA motor. No bump starting here. There is also the spark switch which IIRC is the one Darin made. But this switch, in combination of a clutch switch, simulates auto start like the FAS and it restart automaticly if you go in gear. This switch is not as good as the injector killswitch because when you cut the engine, there is a small amount of unburnt fuel that goes in your catalyst and this is not good on the long term.

If you don't have a clutch switch, when you kill the engine with the killswitch, the Insight restarts automaticly when you depress the switch even after pushing it 3-5 seconds. So this is why there is no way to bump start when you kill the engine with a killswitch on the Insight, and that's why I'll probably won't do a killswitch.
