The wiring is tucked back in a small hole on one end of each light. Just look for the end that has a dab of sealant and you'll know which end the wiring is on.

I replaced the top light on ours last year. The wiring was on the drivers side and very short. I barely had enough excess wire to pull out of the hole and splice in new light. I used a double sided 3M tape for automobile trim to install new light.
