I have 2008 ford f-250 with a dealer installed viper 5900 and what don't like about the install is. When i'd unlock my doors with the factory alarm my headlights would turn for a couple of minutes and i want that back. I imagine i'd need to add another relay to the domelight supervision output but where do i tap into the headlights at. I was just thinking about tapping into the (+) when the headlights are on wire but won't that feed back into the relay. Somebody has had to of figured this out on here. Any help would be appreciated.

all you need to do is tie into the headlight wire using a relay. when the headlights are on while you drive it will not feed back into the realy because that relay will only actvate for a short time after you disarm.
