Ignition switch wiring with donor harness

[Jaguar Engineer]

Does anyone know if the factory five switch will work with a 2002 mustang donor harness? It appears per the wiring diagram, that there is additional functionality with the factory switch beyond a simple 4 wire connection.

my basic kit from Factory five did not come with an ignitions switch, so I purchased a universal switch, something like this https://www.dormanproducts.com/p-13869-85936.aspx
I used a 1996 mustang donor, including the harness. the switch worked in my build, although for the life of me, I have no idea how I made it work; its been about 4 years and my memory has faded. I had to wire in the PATS unit, as described in the build manual. But the dorman switch worked for me.
