trouble with parking lights

[Oziyak]

Hey guys,... I could use a little help here.
I've tested some wires and found the right ones for the parking lights to flash, but the only problem is, is that my control unit doesn't send out any voltage on the white wires unless I hook up something called "headlight on warning" wire. when I tie that wire high,,,, then the white ones controlling the parking lights go high?(12v)

can anyone tell me where I can find this headlight on warning wire? or am I on the right track? the alarm is and oem type called "option group"... basic alarm... the only things I havn't hooked up is the brake wire, headlight on warning, and door triggers.

thanks for any help

cheers
Mark
