Any good pics of wiring the push to start and key switch?

a picture is worth 1000 words

Push to start is a very simple low voltage circuit that activates the starter solenoid as drawn in the diagram below which also shows an optional LED that flashes when the starter is engaged. The key switch, or alternatively toggle switches, are used to manage the state of your ignition P-leads.

Depends on what switch(es) and engine you use. They aren't all the same.

Super easy, actually - key switch (if you want to use one) to activate ignition, push button connects to the starter solenoid.

This is what I’m dealing with i may have to just get in there with a multi-meter.

Yikes! That is anything but intuitive.

Dual PMAGS, if you haven't already, download the PMAG schematics from https://emagair.com/ to map out how PMAGs are powered, grounded, placed into setup mode, configured for different timing curves, etc........ Lots of ways to do it and lots of ways to screw up.

Here is a popular example from Bob Knuckols @ Aeroelectric.com showing how to use two S700-2-10 switches. Note that there is one error in the diagram. Since the PMAGS are self-powered above 900 RPM, the ground wire for the PMAGS needs to be grounded to the engine case, not the firewall.

This can't be adequately answered here. There's no way of knowing the connections without knowing what type of switches those are, and how you plan to install everything. For instance, will you have a test/maintenance switch? I'd like to make a suggestion. This isn't really a Dynon oriented question. Try posting this on the homebuiltairplanes.com or Vans Aircraft forums. They have more members that do engine oriented wiring. We have them here obviously, but your odds will be better on a forum that has more of them. I know the Vans forum has multiple threads on mag wiring.
