I am looking to turn on a few LEDs when I unlock my car with my alarm. A couple under the door handles and possible a few put underneath the door on the outside to light up the ground around the area of the door. I have a Domelight Supervision Relay built into my alarm, -200 mA. I know I have to relay this but not sure how I should hook up a relay to it. I have 12V that I can pull from my amp wire and ground I can tie into anywhere, so that is not a problem, I just don't know how what to hook up to the relay terminals. Thanks for your help.

This is for foglights, but the pinout on the relay is the same:

I'll get a more specific diagram for you in a minute...

Here ya go (had to edit the double post)

Unless the domelight supervision wire is negative (which i think it is) then the 86 pin needs to be hooked to a positive 12V.

^^Good catch. Yeah, that diagram is only if the domelight supervision wire is 12v+

The dome light wire is negative, so 12V will be hooked into 86. Will the dome light supervision wire (85) be enought of a ground to run everything?
