Here you go:
switch:
2000 TOYOTA 4RUNNER 3.4L V6 Electrical-Switch & Relay : Dimmer Switch Auto Parts
as for the lights, I picked them up on here in the for sale section. The kit number is:
PT297-89011
You'll also need the relay that goes in the fuse block (marked FOG) under the hood. You can go to the stealership or look for it online, my advice is online as the stealership in San Francisco wanted $30 + tax.
Part number:
90080-87010
Depending on your preference, you might want to change the bulbs...I went ahead and swapped them out for the PIAA 13556
Hope this helps =)
