headlight trigger wire

[ukApache]

does anyone know which wire under the dash triggers the headlights? i'm trying to hook it up to my alarm to be able to control the lights from the fob (fairly pointless i know ) but i cant seem to find the right wire. i been under there with a voltmeter for ages but when i come to putting 12v to a wire that i think will work i get nothing. please help before

 

cheers

Can't you trace it directly from the switch on the stalk?

 

The wire may well go to earth to switch the headlight relay.

ok i found a trigger wire for the parking lights: on the steering column side of the plug its the wire with clear sleeving, & it goes to ground when the lights are on. really though i want the wire for dipped headlights. i found a red/yellow wire that goes to 12v when dipped switch is on, but it doesnt work just by putting 12v to it. im guessing that one of the other wires (maybe the white/black) has to go to ground at the same time for the lights to work.

 

please can anyone verify this? cheers.

thanks to you both for the replies. i do have a wiring diagram, but not that one (mine is for usa & canada which appears to be slightly different ) i'll see if i can trace it from this one
