Ok so i finished the alarm and remote start portion of this alarm already and id like to hook up the domelight supervision to a relay and connect that to the headlights so that they turn on when unlocking the vehicle like some new vehicles do. I'm honestly so engulfed in this project that I have tunnel vision so I want to make sure I have this right before I wire the relay up. It's a viper 5901 and the vehicle is a 93 civic dx.

Pins 86 & 87 go to fused 12v constant

Pin 85 goes to dome light supervision

Pin 30 goes to the headlight wire near the switch.

Pin 87a is unused.

Any help is greatly appreciated!

You're correct but run a 1N4004 diode across the 85 and 86 terminals, diode band (cathode) towards 86. It protects the Viper.

Read the installation manual, do a search here or online for your vehicle wiring before posting.
