Just trying to see lif both siren and horn can be used at the same time?  Siren is on the black orange and horn on white.

It's the opposite. But also would require rewiring of the ignition harness since the white E1 is currently being used to power 2nd ignition.

 

enable option 12.3. it will give you a (+) on WHITE E1 for the siren, and Horn (-) on orange/black. dont enable this option if white is connected to ignition...
