Keep in mind the low and hi cannot be energized at the same time. The temp sending cannot have ANY overlap.

Yes both relays need to be energized on high speed. The temp control energizes low at 88C then energizes both at 95C. The audi engineers designed it just fine and it works in millions of their cars. lol.
Obviously you can only send power to one fan speed at a time.
What you are not understanding is the temp control has both relays energized on high speed, but it is switching off power to low on the motor. If you wire it as I described.
If it's easier for you to use the toggle then why not? I would rather have it automatic.
edit: you can use any temperature switch or switches to energize high and low speed fan, but I found the audi switch to be an excellent all-in-one solution.

The Volvo controller seems to be the way to go with either the single VW sender or relays with dual Caddy senders.

Ah!!! Probably need to be a member to view it. Sorry! This is the only forum that I've been too that requires a fee to post pics.
Sure, but the Audi sender can be bought at a salvage yard for a couple bucks. I bought 2 relay's with harness from summit for 14 out the door. The only problem is it's a metric thread and I had to buy a tap for 15.
I believe the ebay sender that I linked is an aftermarket that runs at lower temps, when I went to the wreaking yard some of the cars had sensors with higher temps.

Yes, you are probably correct. I'm a newb to this forum. I'm not a newb when it comes to cars and electrical wiring. Just built a TMI recommended 400 for my pops 78 f250 and put the taurus fan on it. I built my supercharged modular Stang. Been driving Fords for 20 years.

Both of the fans I got actually came out of T-birds. I believe they are described in some info that you posted earlier as Mark VIII type assemblies with different motors but they blow waaay more air than any aftermarket fan I've messed with.
As far a sensor locations go a t-stat housing with a threaded bung is a start for one but I haven't figured out the other yet.

That would work fine. I figure you could also put a pipe ell in the manifold outlet for the heater then a pair tee's with the switches in the side ports and the barbed fitting for the heater hose in the end of the second tee. That would maintain the ground but be pretty ugly, especially if you used galvanized pipe fittings. I just hate seeing those in automotive applications.
If my truck doesn't sell before Summer I will probably tee into the heater hose and install some sensors for automatic fan operation. The on-off-on toggle works just fine for me, but if my wife drives the truck the concept of "watching the temp to know when to turn on the fan" doesn't register that well, so I toggle it to LOW-ON and leave it for her.
Which doesn't bother me, but in my mind I think it makes the t-stat work too hard trying to keep the engine warm battling the fan, which is keeping the coolant cold.

That was another thought I had. You just need to try to find a thick spot for larger 3/8" or 1/2" NPT holes.
Why are you selling that badass truck?

The fuel prices of 2008 (Diesel over $5 a gallon) are one of the main reasons I no longer have my 2005 6.0 Powerstroke.
But the main reason is I don't think I will ever drive the truck on a daily basis with 9-12 mpg, but then again a 4 cylinder diesel swap (4bt, Isuzu etc) seems like an idea....

Because of the thickness of the Taurus fan, it may be a problem dodging my w/p pulley.
I have seen a lot of guys with tight spaces use the ford contour dual set up. It is a single speed, dual 12" system.
Does anyone know anything about this set up?The shroud covers more of the rad. too.
