Remote Start DIY Wiring Guide 2006-2010 Yaris

For the (+) IGNITION OUT (TO ALARM) it says:

As an add-on car starter: If connected, disconnect the ignition/accessory
input of the remote controlled security or keyless entry system.
Connect the H1/3 YELLOW ignition output to the ignition/accessory
input of the remote controlled security or keyless entry system. The wire
will prevent the host system from sensing that the ignition is on during
remote start operation.

Should I use the "Disarm No Unlock use key sense wire" ? That requires a negative input not a positive input like this one outputs. Should I get a relay and wire it that way?

Also, the (-) ACTIVATION INPUT,

This input comes from the factory set to 1 activation pulse. This means
that it is necessary to have 1 ground pulse on the white/blue wire for
the remote start to activate or to deactivate. The same holds true for the
remote control activation when set to a two pulse setting it is necessary
to press the button twice for the remote start to activate or deactivate.

I can't quite figure out what that means. Would this input be used if you wanted to use the factory lock button? It has a little diagram about a Momentary switch so I really don't know what its talking about.

Whether the (+)Ignition out is required or not for yours will depend on the particular alarm that you are using. You didn't answer above, as to if it is the factory installed OEM one, or an aftermarket one.

The (-)Activation input is for triggering the remote starter from an existing remote.
