This is great news.
The one thing is my AC works better/gets colder when I switch it to AUTO versus selecting max cold on the temp control. I do this when sitting in traffic and the AC works even harder. Not sure what is going on.

Latest upgrade at no charge
Previously factory fan bushings were not available and we used a piece of inverted hose. Although it worked fine and pasted the test of time it always bother me. I have been working with my local parts guy at Camelback Toyota to find a factory bushing that will work. We found a perfect match and ordered a bunch. Going forward all 100 series fan kits come with factory bushings at no additional cost

Did you do it? Sounds like a cool idea... for now I’m planning to use the switch provided in the kit, but would be an interesting project to have it kick on automatically as needed.

Just look to see if you have a Trinary or Binary switch on your system now. If you have a trinary..then you already have a means to activate it automatically. You would just need to add a couple of pigtail wires to the connector (which is already set up to accept them) and go through a relay.
Wait... You mean that when Toyota removed the extra fan in 2003 and up LCs, they used the original wiring (from 2002 and earlier) so this kit could potentially be plug-and-play?
I don't know what they did. Just pull the connector off of your pressure switch and see if has provisions for four pins. IF it does...you most likely have a Trinary (not Binary) switch and can just add a couple of pigtails (I believe the part number is 82998-12270). I'll have to find my old notes.
IF you already have a Trinary switch then you can use the (mid pressure) function of it to complete the circuit to the fan. It will come on when high side pressure reaches about 220 psi automatically.
Thank you sir! If you could dig up and share your notes, it would be greatly appreciated.
I will check the connector once I get home Monday.

If you go this route make sure you use a relay.
Yes, when we get to the wiring portion....it will necessitate the use of a relay and a fused power source. Lots of different ways to wire it. Not difficult, but each person needs to decide how they want the fan to operate (and when) and how much control they want over it.
So no point discussing that until its time.

Yes lots of options to control an aux fan and our kit uses the simplest, most reliable and easy to understand.
For my needs I like to leave my fan running after the engine shuts off so manual with power always to the switch was my choice.

Wasn't aware you had a 'kit', but that would certainly be the best way for someone to add an Aux fan.
Like you, I prefer for my fan to 'run on' after system shut down. It is a handy feature for times when you just want to jaunt in someplace (less than 30 minutes) and then return to your vehicle. IMO it does help the system purge heat and equalize faster...which means cooler air, faster upon returning to the vehicle.
Manual control would be useful for some folks. Can be accomplished with either the hot or ground circuit.

Yes we offer a simple reliable plug and play kit (2003-2006) modeled after the pre 2003 for the electrically challenged. See #1 post

But like you I like to keep the heat soak down in the summer and for me with solar I dont worry much about the fan running. Uses about the same power as a fridge.
I'm thinking of doing this mod but wondering if you've considered running a relay instead of a switch? I'm thinking of tapping into the 12v supplied to the compressor clutch as the relay trigger so when the compressor is running the fan is on. That would also keep all the wiring in the engine bay.
That is how I wired my kit, compressor on, fan on. Works like a charm!

Nice set up. Again there are many ways to wire the aux fan our approach is the simplest and most reliable. With that said if you have the skills wire it how ever works best for you.
Well, I installed mine today as soon as I got home from our family trip. I never want to be without this extra fan again.
I still have a few things to clean up but it’s installed and works! It really was about a 30 minute job (not counting preparation).
We leave for another week-long trip this Saturday, so I wanted to get up and running as quickly as possible. I am just using the manual switch for now.
@SHIfTHEAD I’d be really interested to know how you end up wiring it to the compressor.
@LandCruiserPhil one suggestion: make the wire which runs from the fuse box to the switch in this kit longer. I ended up having to extend all three, which wasn’t a big deal, but had to dig around to find some wire. Other than that, thank you for putting together this great plug-and-play kit. Toyota should never have removed this auxiliary fan!

Thanks for the feedback to be clear would you like to see the feed wire (red) to the fuse longer or both the feed (red) and ground (black) longer?
Red from fuse to back of switch. There was no way I could have routed it which would have reached the back of the switch.

Thanks red feed wire now adding 6"
