The pictures are a bit large, but I think I can help.

(30) is your ground. (87) is your constant 12V, (87A) should be the switched 12V. (85)(86) are your fog lap leads. The (87) and (87A) could be the other way around, but I doubt it.

Wrong, do not hook it up that way

(85) is groung
(86) is switched power
(30) is to battery
(87) is to both fog lamps
(87A) is unused
