I currently have an Avital 4200 installed in my 1999 Chevrolet Silverado and I am looking to hook up the dome light supervision. I just need to know what wire to tap into to do this and if it is Pos or Neg. Thanks.

You can use the drivers door pin wire.It is located in pin b4 in the bcm,or in the drivers side junction box,with the harness coming from the door.make sure you use a meter and verify.It is a negative trigger doorpin.

some units dont have an internal domelight supervision relay. Wire up a relay and jsut connect it to your door trigger pin

85 - constant 12v

86 - dome light supervision wire form alarm or RS

70 - high current ground

30 - Door pin wire

You do not need a relay. The door pin wires at the BCM are low current. You can connect your domelight supervision wire directly to the drivers tan doorpin wire.
