what is the boot? is that the trunk? umm to unlock i would: 85-12 V : 86-Alarm output : 30 - 12V ; 87 - unlock; But i think thats wrong because i dont understand what you are asking, if the boot is the trunk why would it have a "lock"? If you mean one of the doors then you need to reverse the polarity on the actuatior.. Yo no comprendo. how can a motor perform 2 directions if only one wire is active? Maybe someone else will respond who knows what you are talking about.

Ok Glenn- First of all, the motor you have really isn't suitable for your use- the motor you have is bi-directional. What you really wanted was a solenoid. However, I think you can modify it and make it work. What you would want to do is add some sort of spring load so it will return to a "rest" state. A fairly soft spring should do the trick- if you go too stiff, the motor will have trouble overcoming the spring, eventually burning out. Also, when you hook it up, you'll need to ground the wire you don't hook to the relay. The hookup is easy- your trigger wire to 85. A fused lead (say 16ga, w/ a 10A fuse) to 30. Loop a tap from 30 to 86. 87 to the lead on the motor that gives you operation in the direction you want.

i come from the uk and we call the trunk the boot over here so yeah sorry i should have been more clear but thanks for replying guys.

when you say loop a tap from 30 to 86 do u mean i need a perm live going to both terminals. im not that clued up on wiring relays so i just want to make sure i do it right

thanks in advance

Yeah- that's exactly what I mean. Since your alarm gives a control ground, the relay will only operate when you

tell the alarm to operate it. If the pulse from your alarm were positive, your hookup would be different, but the result the same. I'm curious- what are you fitting this to?
