Have you used factory hood switch? This sits on ground when shut and open circuit when hood lifted; you will need to fit another switch. I believe the trunk switch is pos, you will need to flip the polarity to neg (Check these two)

I didn't use the factory hood switch. I connected the alarms -gray wire directly to my pin switch under my hood.
I already used a relay for the trunk pin/trigger alarm was -blue connected to cars +WHITE/ yellow(I used the 451m relay for this. Small red to +WHITE/ yellow in car, Small blue and Large purple to ground, Large blue to Alarms -blue.)
I also used a relay for trunk release, but don't remember how I hooked it up. car side was -WHITE/ violet, alarm was -RED / white.

Never mind, I had it set up wrong on my lcd remote pager settings. I had it set to say trunk and hood were open, instead of just trunk. So everything works now. Thanks for the help.

I have another ? about my trunk release wires. I just disconnected the relay and touched the two wires together for trunk release and it works. Would their be any problem with just connecting these wires, or do I really need to keep them on the relay? Does it need the relay to prevent falsing?

I hooked up my dome light supervision to a relay, but the lights only work sometimes. I have a 12v constant source tied to a 10k resistor on the dome light wire in the car(to prevent falsing, I also used it as my door trigger) Would this be causing it to work sometimes and fail most of the time?

I just tried using a relay for the door trigger. I hooked it up like this 86 to (driver door pin GREEN/ black), 85 to 12v, 87 to ground, 30 to -green alarm door trigger wire. When I had the door closed it paged me that it was open. When I opened the door it said it was closed. Any Ideas? I really need to get this alarm working. The door pin doesn't work and the domelight supervision doesn't work right either. Please help me out.

Check the door trigger initially, see that it goes to ground only on opening the door; if thats OK then you are looking at an alarm problem or something is touching ground on your alarm. Relay is correctly wired but not needed, try a diode between your wgreen wiring connection and the CPU in R/H kickwell with stripe on (1N4001) facing the connection.

Ok I just disconnected the dome light relay cause it doesn't work right(I think because my car has a delay in the domelights)
With the two individual door triggers I hooked both of them up to the relay. But they don't work. Keeps paging door is open when its actually closed, and says closed when both doors are open. I used driver door +GREEN/ black pass door +YELLOW /GREEN. They are positive cause when doors are closed they are at 0 and when the door opens they go to 12v. Any ideas, maybe I need to hook up the relay differently since they are + and not negative like the dome super wire?

If they are positive, join them via diodes, band towards alarm diode type 1N4001 and join to alarm's PURPLE wire.
