well iirc its a negative trigger so you need the

2 negative wires on the alarm

and if you look on the wiring loom you just put in then you will see

a yellow wire and

a white wire

i think yellow is unlock
and the white one lock

you would connect these wires to the together just behind where the glove box would be that way can't be easily traced or got to without taking dash out

also the boot you could use a central lock motor as normal but DO NOT CONNECT TO MAIN LOOM use the unlock wire and earth this to bodywork then connect the red wire i think it is and connect this with the grey aux channel a wire of the alarm system

hope this helps thanx alain
