Not sure if this is any value to anyone, but the switch part number is 84160-38010. No amp rating listed on it (maybe someone knows), but it allows you to have a finished look for interior LED's etc. The stock foglight kit uses a relay, so if you're gonna wire up something electrically demanding, you probably better go the same route. I was told that stock foglight relay alone is $60. Someone at Toyota/Scion is smokin' crack!!!

Thanks for all the great info on this site!!
