Thanks for the reply. I too have installed the footwell lights and I used the information in your post to accomplish this. Thank you. However, for what I'm trying to do with the courtesy lights, if I used the same wire, the courtesy lights would come on when I turn on the interior dome lights. I'd like to avoid that if possible, so I'm looking for a source that would send a current to relay when the doors are unlocked and/or opened but not be tied to the interior dome light being turned on. Not sure if this is possible? My other option would be a source that energizes the relay just when the doors are unlocked. My last resort would be to use the footwell light wire as a trigger. Thanks again.
