Noob here and cautious so after looking around the site, I haven't seen exactly what I'm looking to achieve and will explain as detailed as possible.
I appreciate the assistance in advance.
1993 Ford Mustang street / strip with manual transmission and carburetor.
I currently have a nitrous system, armed with a keyed 12 volt toggle switch, wide open throttle switch and MSD 8956 RPM Window Switch witch all works great.
Currently wired up like the image below
I also have installed a 4 toggle switch panel to isolate each function (Nitrous, Line Lock, 2-Step and 3-Step) which all work independently right now.
(I'm using a MSD 8737 three step)
I also have a momentary push button in the mix (currently not in use).
Here's what I want to achieve:
Option to activate each system combined with others or independently (selectable with the toggle switches).
Burn Out: Arm the Line Lock and Two Step by turning on two toggle switches and pressing the momentary switch, release the momentary switch and both systems deactivate.
Staging / Launch: Arm the Line Lock, Three Step and Nitrous by turning on three toggle switches and pressing the momentary switch as a latching switch to activate the clutch so the clutch depressed alone will keep the systems active while the Nitrous is inactive. Release the clutch, the three step and line lock deactivate and the nitrous activates (through all mentioned components in system above). The clutch switch should only work during the launch (not while shifting).
