alarm wiring renault megane 05

hi i have an renault megane 05 reg and have fitted a cobra 3193 alarm to it which all works fine but i need it to put the windows up on arming.

i have located a wire in the cars control box which is grey  PE2 socket TRACK 7 which is called (one touch electric window wire) according to wiring diagram of car

problem is i cant get it to work from this wire

i have tried direct negative feed to this wire and nothing happens but if i manually pulse it by dabbing a negative to the wire all the windows close.

i cant use a pulsing relay as the grey wire seems to have no sequence as i tried 1 second on 1 second off 3 0r 4 times then tried 2 seconds on 2 seconds off   and nothing

just seems to work when it feels like when i dab a negative to it

if anyone understands this and knows anything at all about my problem then please help

there must be some smart a*se out there
