alright, the wiring on the bottom: the red and white wires hook up to the open slots under the fusebox under the dash, the black wire on that harness hooks up to the switch, then you use a bolt to mount the relay under the dash. There is already a thread on here telling which one goes where. just look in the following links to my installation instructions. (pg. 3/4 for underdash wiring.)

The other harness is for the lights (duh) the harness is supposed to be ran vertically with the drivers side of the ac condensor. Then the black ground hooks up to the frame section next to the headlights (there should already be another ground already there. The red power wire clips up to a clip that is already in your engine bay, you have to find it near the headlight harness and the windshield spray reservior.

the pics are for a 96-98 model, but same principle for 99-00 with the exception of the actual fog light housing.
