I used Bruce's great idea.
Use the relay for the factory fogs to power the relay PIAA included.
I basically scrapped the included harness, it wasn't long enough to reach the lamps, and still use my aux fuse panel. I wired the power from the new aux panel, and ran the switch power lead to the factory fog relay. Now I can use the factory switch. It powers the original relay, which powers up the PIAA relay which gives juice to the 520's. Nice.
This morning I also replaced the bulbs behind the lcd inside the climate control. Working good now! Though Toyota parts did not have a clue as to which bulbs they were. It turns out that they have about 4 options on their computer. I ordered some yesterday, went in this morning and they had a different socket than the ones I removed. So the parts guy just took them back and eye-balled a replacement. One that was not even on the computer for that application. They fit perfectly and seem to work great.

 

my cc bulbs just went out over the weekend. any idea for the part number?

 

Your rig looks awesome George. I am so jealous - man I need a bumper!

 

Here is what I put in
# 90072-02009
The LTD has different climate control than the SR5. So, Hopefully (if there was no change between 99 & 2000) this should work for you.

 

Looking good there George with all the moddage! It's beginning to look like a trail rig!
