Looks pretty straight forward...stick in appropriate place, black wire to ground, other wire to power source. If you want them on any time car is running tap into "key on" power source, on with running lights tap into running light power source, on with headlights tap into headlight power source or run a switch to turn them on as needed....probably much easier than any stereo install.
Looks like they would fit nicely in the rubber strip gap below the headlight.
