couple 05 equinox starter

so i used to install a lot of starters till about 03 so im a little rusty.i have this cheapie alert rs90 and a omega ib-pjlx bypass that I wanted to put in my gf equinox.theres already a non working,no remote set up in there I have to remove but before I waste my time....I see there is no start wire,does the bypass start it or I think I heard something that it cranks when sees power to ign wire but not acc.this start has little program option has two ign output,1 acc output.no way to turn off at start.so if bypass starts it can I use second ign out put and acc output for the two acc wires?then there is no ground output while run(I believe) just ground pulse factory disarm so can I use relay off ign output swithing to neg to activate bypass?or if I need a whole new unit what options do I need to make sure it has. thanks

actually it does have ground output while running but is may ign acc outputs an issue? thanks
