I actually installed the fan last spring but didn't take any pics at the time. I originally had it setup to manually but recently bought a Hayden controller setup and wired it in. Since it was apart at the time I took some pics.
For the physical install I actually bolted the Taurus into the stock V8 shroud using self tapping screws. The bottom of the shroud opening needed to be opened up a bit but not much. Doing it this way allows me to simply drop the fan assembly back into the stock mounting points, no custom fabbing needed. Also its super fast to pull the fan for repairs(belt replacement, etc) or to hose out the rad at the car wash, just pull the two 10mm nuts holding the shroud on.
The hole was drilled with a hole saw to allow the stock plug to pass thru. I kept as much of the original wiring as possible.
Including the fuse and holder. I'm running a 40amp fuse. You can see it in the pic bolted to the battery hold down bolt.
Sorry thats it for pics. I'll do a quick writeup of the wiring.
Getting a relay that can handle that much power is essential. I've seen lots of people have trouble on the trail because they used a 30amp Bosch relay like for offroad lights. Its not big enough for the Taurus fan. The easiest to find is a selonoid like for a starter, but it must but rated for continuous duty, similar to the ones used for winches or dual battery setups. They are easiest to find in the RV section of most autopart stores.
The setup is controlled by a 3 way switch on the center console next to the shifter. Off is center, up is on(override), and down is automatic.
The Hayden controller is powered by the 3 way switch when in automatic. It is the type that has a probe in the fins on the rad. When the preset temp is reached it triggers the solenoid for the fan. It also has an auxiliary wire tied into the AC clutch wire to activate it when the AC pump is engaged.
The other wire from the 3way switch goes directly to the solenoid and activates it regardless of what the Hayden controller is doing, no power actually goes to the controller in this position.
When the 3 way switch is in the off position no power goes to the Hayden controller and the unit will not activate.
I'm actually only using the "high" function of the Taurus fan, wiring in the low side was too complicated as you need a lockout to prevent the low and high from coming on at the same time. Also when I had it wired up manually low didn't seem to do much.
So far its been a good mod, only draw back is that it does suck back the power. I worry about draining the battery at idle and I will mostly likely upgrade the alt very soon. Warm up at cold temps are. super fast, 5 min to operating temp at -25C. I still had some overheating issues with it last summer but I think my rad maybe plugged with mud and I usually forgot to engage the fan till it was getting hot(3/4 mark+). However simply stopping and idling for a few minutes brings the temps back down super quick.
A good upgrade though and I like how easy it is to work on the engine. I've had to do an alt and PS pump since it went on and not having the mechanical fan in the way makes it easy to work on.
I've been carrying the mechanical fan for a a few months now as a back up, since the shroud is still there it would be easy to put back on, but its been working pretty good since the Hayden controller went in so I think I can leave it a home now.
I did fry my alt after putting it in intially. But I didn't have the controller on so I was prone to just turning the fan on and leaving it on. The 2nd alt was a stock used one and with the controller seems to be working fine. However I have not tried it in hot temps yet and hope to have an upgraded alt and pssoibly dual batteries in before next summer.
