Thought I'd post an update.
I got the Performance Products Hella fog lamps and they are in fact the exact same ones that come from Toyota.
Rather than do any splicing of wires to install the switch that was included with the kit, I purchased a factory head light switch (called a dimmer switch) that included the fog light collar. The cost was about $60 shipped, but made the entire fog light install plug and play. The new dimmer switch took all of 10 minutes to install.
I also did the re-wiring to allow the fog lights to work with the parking lamps as well as the high beams.
Since I used a factory dimmer switch to control the fog lamps, I was able to use the switch included in the fog light kit as a DRL switch, and did that mod at the same time.
I like things to look absolutely factory, so I did the more involved modification of taking the engine bay fuse box out and re-wiring the under side of that. I doubt even a toyota tech could tell this mod wasn't from the factory without some digging.
Both mods were pretty simple to do. I soldered all the connections and used plenty of electrical tape and heat shrink for protection.
I followed these articles to complete the modifications:
