alarm light flash

i have a 1990 nissan pathfinder, and i have a alpine sec-100s alarm, i want the headlights to come on when i arm and disarm it. I have had the left front head light working for a few months, and i decided to go back under there to see how to hook up the right head light too.  There is a left and a right wire under my dash, i tryed hooking them both up to the alarm at the same time, but the right one stoped working when the engine was on.  So now im guessing i need to rig up a relay to do so, but im not too relay smart, could you guys help me out.

Thanks

hey there first you need to isolate them so you are going to need2 relays, one for each light.

on one relay do this....87-12v (+) batt.

                                        85 and 86 will get a pos and a neg.so if you are useing a neg. trigger on 85 the 86 will geta pos. opposit if  you are using a pos trigger.

                                       30- will go out to one of the headlight wires(the wire colors are RED / green and RED / black

   you do the same setup on the other wire.

I hope you can understan me im not to good at this without doing this and showing

  goodluck, mark
