There's basically no instructions besides the wiring chart. I've read around online and everyone hates the automatic arming and there's no way to permanently disable it.Also, if I'm reading the diagram correctly... The only way the engine will die on you is if You lose battery power. So, if you are worried about that "Chinese junk" being near your ignition and what not due to random engine cut off due to failure or what not... I don't see that happening.
