how to wire in kill switch?

[DIESELMAFIAPER.LB7]

tech said this year all 2.6 trucks need a fuel or air shut off how are you guys doing this for a fuel cut off? I was thinking of tapping into the ecm power feed somehow? then running a switch to the back of the truck for the sled to hook to.

I don't like the idea of it but whatever looking for ideas of what you pullers have done thanks

Does it have to be a mechanical shutoff? I am not sure why the ignition wouldn't count.

I have to have either a air or fuel shut off (which in our case is electronics) could tie to the ignition o ecm power I guess once those go off everything stops so

Your best bet would be to kill the air supply, doing a fuel switch sounds way too tricky, unless you use a dsp2 switch and just write a tune with no fuel and call it a kill switch?

All you need to do is interrupt the power to the ecm and you'd have cut the fuel. However for a true fail safe, cutting the air supply is the safest option.

Not doing a air cut off on my dd lol time to dig the manual out and find some wires

if you suffer an internal engine failure of some sort and engine oil is able to get up into the top of those cylinders your engine will run away and blow up unless you can shut the air off.even a turbo failure can sometimes allow enough oil to get into the engine to let it run away.

don't have one, not buying one, not refabbing my intake for one. that's the only instance a duramax runs away freak things.

what did you put it to just a toggle switch in the back?

I never actually ended up doing it yet. Alot of guys use a trailer break away switch to do it. I have a air shutoff, but might still add a ECM kill switch also.

I was looking at one of these:
