python 460hp into 92 legend

I had this alarm laying around and decided to install it since the factory keyless remotes are broken. I would like to incorporate this aftermarket alarm with the factory alarm because it has a factory starter kill and i dont feel like wiring up a separate relay. As for the trunk release and trunk pin, what two wires off the 460hp alarm do I use?

i found this thread. https://www.the12volt.com/installbay/forum_posts.asp?tid=521&DIR=P&fid=3 looks like the (-) wire is used. then what would i connect the (+) for door switch wire too?

You don't connect the positive trigger to anything, period, cut and isolate,

I read the reference guide wrong. When arming the python alarm, would this also arm the factory alarm? I would like to retain the factory ignition kill feature.

Would the factory alarm work alongside my python alarm? Such as, disarming and unlocking and vice versa? If that is the case, would the factory ignition kill be functional without adding another relay?
