Car Alarms: Subaru Impreza - Disable alarm with remote starter?, negative pulse, remote starter

Question
I’m looking for installation wiring info/help for the OEM keyless entry part # h7110as011 in my 2000 Subaru. I just bought a 2000 Subaru Impreza with the factory Keyless entry and an aftermarket Omega RS-7K2 remote starter in it. They are both wired independently and functioning. I also just put the OEM security system upgrade in. I need to disable the alarm to use the remote start (ignition kill not a problem the way it is wired). The remote starter has a function that will disable an OEM keyless/alarm with a negative pulse. I don’t have the keyless install info and don’t know where to connect it. I did find a mostly complete keyless pinout detail kindly posted at:

The remote start will also accept a pulse from the OEM keyless to activate - I got this working, so I can start my car from a short distance away by 2 pulses to unlock the doors. But, I would rather disable the alarm since the remote starter transmitter has a greater range.

Can you tell me how to connect to disable the alarm in this OEM keyless/alarm with the remote starter?

Any help would be appreciated. Thanks.

I am not sure, the person who made the page you reference appears to have really done their homework.  I looks as if there may not be a disarm input for your specific vehicle.
