2001 domelights supervision

I have a 2001 ford escape that I want to install an Excalibur AL-1850. My truck has a 5-wire (-) domelight supervision wire, that per the 12volt it needs a relay wired as follow.. The alarm unit that I have does not have a domelight supervision wire it only has and onboard relay, that its read as follow: BLACK/ Red Wire - Light Relay N/O (+/-) Input GREEN/ Violet Wire- Light Relay COM Output WHITE/ Red Wire - Light Relay N/C Input So how would I wire the domelight wire.Knowledge is Power.

if you go to this link you will see how 12volt has the domelight for the escape wired. http://diagrams.marktoonen.nl/DOWNLOADS/26500_ESCAPE-_ESCAPE%20DOMELIGHT%20SUPERVISION%20DIAGRAM.pdfKnowledge is Power.

So the equivalent relay terminals for your alarm as as follows: Relay Terminal 30--Alarm COM wire Relay Terminal 87a--Alarm NC wire Relay Terminal 87--Alarm NO wire The Dome light wire is listed as: Dome Light   L GREEN/ ORANGE (-)   PIN 1 OF GEM MODULE ** You would cut the Lt GREEN/ Orange dome light wire. Connect one side of the cut dome light wire to the alarm's COM output wire; Connect the other side of the cut wire to the alarms NC wire. The NO wire from the alarm is not used. Lectric Guy

Thanks lectricguy, now im ready to install this alarm....Knowledge is Power.

lectrichuy one quick question before I start, when I cut the domelight wire does it matter on which side of the cut domewire the relay terminal 30 is connected to????Knowledge is Power.

No...You are connecting relay contacts (Similar to a switch) between the two cut wires. No polarity concerns.Lectric Guy

ok, thanks....Knowledge is Power.
