Hello, I'm replacing a failed remote starter with a new Excalibur in a 2002 Silverado base 2 door truck. I'm confused on how to wire in dome light supervision. There are three wires from the alarm as it has a built in relay. Any help would be greatly appreciated. This is my first alarm install, everything else works, I can't seem to figure this one out.....

Here is the Dome Light Relay info from the 1850 EDPB install guide :
BLACK/ Red Wire        Pin 87
GREEN/ Violet Wire     Pin 30
WHITE/ Red Wire        Pin 87a

Here is Dome Light Supervision wire info :
From ReadyRemote :
Dome Supervision gray/black (dome lamp), dk. green (puddle lamp) (-)    @ BCM, lt. blue plug, pins A3 and A8
From Bulldog Security :
DOMELIGHT SUPERVISION TAN (-)   @ BCM, PURPLE PLUG, PIN B4,

Seems that you will need a (-) Dome Light Supervision output from the Excalibur system. Connect the BLACK/ Red wire to chassis ground and the GREEN/ Violet wire to the
correct wire in the truck. The WHITE/ Red wire is not used, so just insulate it.

Soldering is fun!
