Chase....not a puzzle at all. Do you own a coat hanger? Remove the existing lite. Take a coat hanger and push it through the existing hole in the direction you want to install the new lite and see how far it goes. If there are not any obstructions, you are good to go. Drill a hole big enough, maybe a 1" hole, where you want the new lite. Then move the coat hanger around until it hits your finger. Pull it through the new hole with new wire that is taped to the CH that is long enough to hook to the old lite wires and leave you plenty of wire to install the new lite. I would use #16 ga wire and some good butt connectors. If you need more help...PM me.
