Still need some alarm help

1 - Yes use a relay, check the dome light, it should be negative switched. Use a relay to switch the appropate wire to ground. 2 - No you don't need a relay, Use the wire that shows 12volts when the light is on, make sure you hook it up to a +12v input to the alarm as the auto page alarms usually have several inputs, some neg switched, some postive switched.

do you have a diagram on how to wire the relay??

if the dome light is negative switched... on the relay pin 30 goes to ground, pin 87 goes to the dome light wire pin 85 goes to +12v via a fuse, or hook it up between the fuse and the alarm on the autopoge 750. pin 86 goes to the domelight supervision connection from the alarm - white wire #H5 pin white connector I think, but check if the dome light is postive switched... (not the normal) on the relay pin 30 goes to +12v, pin 87 goes to the dome light wire pin 85 goes to +12v via a fuse, or hook it up between the fuse and the alarm on the autopoge 750. pin 86 goes to the domelight supervision connection from the alarm - white wire #H5 pin white connector I think, but check. I hope that helps, the install manual should show a diagram. Greg
