2004 Mustang GT installing Python 533

I am in the process of prepping everything to install a Python 533 into my Mustang and had a couple of questions before the installation. From the wiring diagrams I've found on here and bulldog it appears there are two ignition and two accessory wires. The alarm unit has a selectable output for a second ignition or accessory circuit. I'll need to use a relay setup to power the other ignition or accessory circuit that is not included, correct? Would that be the purpose of one of these: PINK/WHITE (-) 200mA PROGRAMMABLE IGN2/ACC2 RELAY TURN ON YELLOW (+) IGNITION INPUT TO ALARM PINK (-) 200mA IGNITION RELAY TURN ON ORANGE (-) 200mA ACCESSORY RELAY TURN ON PURPLE (-) 200mA STARTER RELAY TURN ON ORANGE / BLACK (-) ANTIGRIND/GROUND WHEN ARMED OUTPUT BLUE (-) 200 mA STATUS OUTPUT There are also both a + and - parking light wire listed in the diagram. The unit has an output that is selectable to + or -. Do I need to tie into both the wires in the car, or just one or the other?

Use the selectable output for second ignition then relay the orange 200mA output. Don't know the vehicle but I'd use the Pythons NEG output.
