Car Alarms: door trigger wire and dome light wire, resident technicians, ebay

Question
Recently I bought a car alarm from ebay...brand is "option group"...the alarm diagram isn't very clear.  I have a 97 acura integra. this unit has 2 identical wires for flashing lights(park lights)...but my integra only has one wire for parking lights...so will i have to use both or just one of the wires from the unit?  Second, the unit also has a pos and neg wire for door trigger but no wires for dome illumination, my integra uses the door (-)triger for dome light..so would i technically need a relay to get this done?  I don't know if this unit has relays built within the board and don't know how to test it out as there is little description on it.  I'm kinda confuse when to use a relay and when not to besides using it when you want to reverse polarity of the signal...any input will help.  thanks.

Answer
Hmmmm, On this one, the best thing here is
to go to my installers forum at
www.installsupport.com and see if
my resident technicians there can assist
with this project.

I unfortunately don't know the
system you are working with to advise
you properly on it's functions,
features, or trouble shooting
information. Better to check with a tech
that might.

Good luck there.
