momentary to kill power circuit?

ok here is what i have. i have an ignition power circuit that i need to be able to kill with a momentary ground input from a switch. this ignition power circuit needs to function as normal until the - momentary input is received from the switch then resume power when a second - momentary pulse is received. i have looked at the momentary on/off latching set up and the starter kill setup and neither seem to be what i need and combining the two seems way overly complicated. this should be fairly simple but for some reason it has had be banging my head on the wall today. thnks in advance for any help or advice.the creation of technology and flow of power is the 12volt source of my soul.

use a 3rd relay as your switchJohn DeRosa (Hotwaterwizard)

When in doubt, try it out !

forgive me but how will that work? and what do you mean by use a third as my switch? the switch i am using is part of one of the factory systems. when pushed it gives a momentary ground to the module in the truck. so i need to be able to use that momentary ground pulse to kill a key on ignition circuit for one of the other modules. but that circuit needs to operate hot until that switch is pushed and then be able to resume when switch is pushed again. what do the latch and unlatch terminals on your diagram go to? thank you.the creation of technology and flow of power is the 12volt source of my soul.

See if this works for you- https://www.the12volt.com/installbay/forum_posts.asp?tid=89844&PN=1 If this is something you're planning to use on standby battery power you'll have to take relay draw into consideration unless you get a mechanical impulse relay that holds the position without drawing current.
