For the life of me I cannot figure this out. I wired my entire alarm in over the winter works great w/ the exception of the trunk trigger wire. Instructions tell me I need a neg trigger. The only thing I can find on the car for a trunk trigger is the black/pink wire...I looked at some diagrams and I think this is a + trigger. So I used a relay and converted the + output of this wire (black/pink) to a - and the trunk trigger still doesn't work right and I can't understand it. I'm thinking w/ the relay it should work correctly. If I connect the trunk trigger wires and arm the system it won't arm b/c it thinks there is an open zone (ie the trunk is open) although it is indeed closed. It's a pretty minor thing but there must be a way to get this working.
