This is my first post and need help from the pros.  Not very good with electrical systems.

I am using a momentary switch for nitrous activation.  I need it so I can push the button and have the system stay on, until the ground is cut via a wide open throttle switch.  The the thing i don't understand is how to make the latching relay reset it's self after it completes a cycle.  I need it to reset it's self, so when I go back to full throttle the nitrous will not re-activate.  So it requires pushing the button again to activate.

Any schematics or list of parts would be awesome.  Thanks

you will need one more relay hooked to your open throttle switch, so when it is triggered it will send a pulse back to the momentary switch to disengage the latching. you will also need it to cut the signal off so the open throttle switch doesnt keep activating the latched relay as well.

There are 10 types of people in the world, ones that understand binary and ones that dont.

When power is dropped the relay resets it's self automaticly.

just hook the ground where you hook the ground  that is cut by the throttle switch.

does anyone have a schematic diagram of a remote start  module with about 3to 6 relays with diodes
