I think he means use a separate power source ...Meaning where did you get 12 volts for relay...?But i did just wake up and i havent had a cup of coffee yet...

Is this a trunk release or a lock and unlock solenoid, such as a door lock and unlock?  If it is lock and unlock, it could be a reversal rest at ground setup.  Try cutting that wire, and connecting your wire to the end of it that goes to the solenoid.  If it works with the alarm now, we will have to draw you a new diagram for your relay.  Let me know if it works now.  And remember DO NOT use a larger fuse.

If it works with the alarm, wire the relay as follows.  Power to 86 and 87.  Alarm wire to 85.  The wire you cut goes as follows.  30 goes to the solenoid.  87A goes to the car end of that wire.

It is a 5 wire trunk release motor (09 Corolla). It finally worked when I isolated the trunk release wire through the relay.
30 --- Trunk release (car motor side)
85 --- (-) alarm input
86 --- Fused 12V
87 --- Fused 12V
87a---Trunk release (car switch side)
Seems like the car's trunk release switch rests at GND and you cannot apply 12V directly to the trunk release, hence all the popped fuses. You have all been very helpful. Big thanks.

Wait a minute, I've solved someone else's problem without thinking and we haven't even had Corollas in Europe for 3 years (it's called the Auris) I'm bad. (And no false modesty)
