negative headlights

ok i want my headlights to turn on with the diss arm alarm is a viper 771xvr i have it connected to the dome light supervision. but my relay that i hooked up is a pos output how do i make it into a neg output with the first relay being a pos output.(96 honda accord headlights rest at 12volt turn on with a ground)

86&30 12 volt

85 to dome light

87 to headlights (but its a pos output i need to know if i have to connect another relay to have a neg output)

all you have to do is change how the relay is hooked up and triggered to change voltage. take 85 and hook that up to the domelight supervision wire (BLACK/ white), 86 goes to 12v, 87 goes to ground, 30 goes to headlights.

that worked but now i dont like it lol!!!!!!!!!!!!!!!!!!!cuz my head lights and my reverse lights turn on when i turn off my car (thats how i have it wired) oh well i learned something new thats kool!!!!!!!!! at least when someone else wants it done ill know how to do it.
