Something like this will work. I would use a 68+ driver side jamb switch so that the light alarm and courtesy light circuits are separate. It's a good idea to use a fuse on the IGN connection, as suggested by Coppertop, and you can attach the chime black wire to a permanent ground as opposed to connection to the jamb switch.
