This is going to have to be my next step.
Cooling efforts pay dividends for my SC'd rig

This is all that is needed as I understand it. I'm order parts, so if I'm missing something, post it up.

Random question for you...do you have any video/audio clips of your S/C setup? I've looked all over the internet (ex. youtube, yahoo, google, etc.) and have yet to find a single video file of a S/C'd 80 series.
Commonly used for the SuperCharger installs. I "think" the 3.0 refers to the 3.0 L 4Runner it comes off of.

Doesn't show the SC, but there are a few videos on there of the truck in action. Not sure if this answers your question.

Yup, that's the one. I can't recall the thread (I believe it's a cdan thread though). Honestly, this mod produced the least noticeable difference to me. However, if there is any truth to the ringed fans being a projectile hazard, I guess it's worth it.
That's what I'm looking for. I was more interested to hear what it sounds like in action. I'll have to check those out when I get home.

Please forgive my exhaust. It sounded great when I bought it. Since then the y-pipe is split again, and the muffler and piece that dips below the frame rail I've added some custom "extra exhaust ports".
Looking at doing this mod and I am wondering:
What is the benefit of buying the fan/relay and wiring it up as you (and Sumotoy) did is
VS
Buying the fan and one of the Derale Adjustable Fan Thermo Senson Switch Kits #16759 dealyos would be?
If I read correctly, the first way allows the fan to be primarily controlled by the AC unit/pressure switch. I.E. the fan will only turn on when the AC is on and during certain AC parameters.
The second way presented would allow the fan to be controlled by a thermostat at an adjustable setting of 150-240F and shut off of 10F less than turn on setting. Say 195F or 200F on and 10F less than that for off. This would allow the fan to come on at a certain temp regardless of the AC, which for me might be important when I am towing the popup up mountain passes and the AC isn't on
I read in Sumotoy's write up where a person could add a switch in the cab to control the fan's operation as well but I like simple and the thermostat seems to offer simple, with the negative being that you couldn't shut the fan down if you desired (say a water crossing)...I suppose when towing I could turn the AC on to get the fan to come on but that would be more load on the engine when I really need most of it going to providing power to pull the popup up the hill
Thoughts?

The first way will actually kick the fan on/off based on the temp of the AC system. It isn't controlled by the AC unit directly. It's actually rather similar to running a probe through the condenser, and controlling the fan off that.
The difference is that it's a cleaner install, and you're relying more on Toyota equip than you are on after market.
I would recommend to install it the way SUMOTOY recommended, and then if you want more control also wire in a switch. That way you can manually trigger the fan if needed.

I spent a lot of time overthinking this. In the end, I went with the pressure switch for a couple reasons:
- It's superclean (and easy) using factory switching.
- Even though theorectically it can run with the AC off, I haven't experienced that. Therefore, when I come to a deeper water crossing (maybe twice a year), I can ensure that the fan is off.
- I didn't want to stick a probe in my radiator.
- I didn't want an on/off switch because I'm a knucklehead and would leave it on.
Good points and thank you for overthinking it already

No changing the blade around necessary. Just test rhe polarity with a booster pack or jumper cables amd label which wire needs to be your +.
Makse sure when you switch the polarity during testing you wait for the fan to stop spinning before you reverse it to avoid any possible damage to the electric motor.

Nice job on this.
I elected to use an on/off switch that I manually control. There have been times when wheeling, were I have left the fan running while we ate lunch with the truck off intentionally.
If the fan is on and you turn off the truck and get out, its loud enough that you will notice and shut off
I also during long hauls up vail pass towing have turned it on when the AC is off
But like stated, you should do what works best for you

Just added the 14" fan with a switch, barely fit but it does. Here are some pics, not the best though forgot to take one with the grill off.

FYI the biggest single improvement in cooling I have had so far was when i took the 6 inch lights off the bumper. With my supercharger I would get 210+ temps even in rainy 60deg. days if I was towing a light trailer, removing the lights instantly fixed that. While that is not my only cooling mod I now only have problems when I am pulling over 3500lbs inside Mt. Raineer Nat. Park (5000+ ft @ 30mph w/ 6%+ grade) in the summer.
