Factory Fog Lights

What all is needed to add the factory fog lights to my 2000 Rodeo if i get them from the local salvage yard? Just the lights/brackets and dash switch or is there a relay or anything else. IT looks like the truck is pre-wired for them from the factory.

Yup, you need a relay too. I bought the factory light kit from a dealer and it bolts on and plugs in. a Salvage yard is a good place to look. I think the kit cost about 180 bucks (I got lucky and found a Honda dealer closing out a kit for 60 bucks).
