Electric fan install- easy or HARD ??
I m thinking about getting electric fan from Troyer for my birthday gift..
I have 5.4L 2004 FX4 screw.
I m pretty good with hands but i m alrite with wirings..
Is it tough to do or its easy but taking a lot of time?
If any one already has installed- how long does it takes you from start to finish ??
Whats require tools for installation ?? special tool??
Thanks!

i HIGHLY recommend buying an efan controller from MadFerrarista. www.madenterprise.com great service and and EVEN BETTER PRODUCT. i have had no problems and it was a sinch to install!
copy for my post from another forum.
Ls1 fan setup, can be found off ebay for 75-100$
Then I went to my local auto parts store and bought a Hayden 3647 Adjustable Thermostatic Fan Control for +-$30. This kit is a 30 amp device that has the a/c relay, so one fan comes on weather the a/c is on/off, while the other comes on/off at a certain temp you preset. I mounted it to the side of the raidator off a bracket I made to help keep it cool and for a cleaner install.
You will also need some extra wiring. Some smaller gauge, but you do want a bigger gauge for the ground wires.
Optional Supply:
Also bought a Littelfuse Mini Add-a Circuit setup. $4 roughly. This is a option because I used a 3 way AOM switch for my 2nd fan.
Taking off the old:
Take off your black cover that fits over the raid etc.(youll know what im talking about). Then you will need to take off the OEM fan. This is a PAIN! If you have the propper tools im sure it would be easy, but I didnt at the time. I used a BIG pair of pliars and a water pipe wrench. It took one person to hold the pliar and one for the wrench. Put the pliars on the bolts that hold the water pump pully on and the pipe wrench on the fan. Once its broke loose you can take it off by hand. Then just undo the 2 bolts that hold on the fan guard and work it out. It takes some work but it can be done without taking the water hose off the raid.
Installation:
The mods I had to do with the fan assembly is cut off the middle tab on the bottom. Also on the side that faces the raid, I widdled down a ridge so the fan assembly will fit snug against the raid. To mount it you could just easily use wire tires, but I chose to bend up some brackets out of aluminium.
As far as wiring it up. I hooked the 2 grounds for the fans and the ground for the Hayden kit to a factory ground point on the passanger side fender. I hooked the red and yellow wire of the hayden kit directly to the battery. The orange and blue wire to each fan, doesnt matter which, it's up to you. The green wire I ran to the driver side of the truck where there is a easy access to a rubber plug. I have not found a good place to hook it up to the a/c yet. So if anyone knows share the information!
Optional install:
I drilled a hole in the access plug and stuck the green wire through, then ran it to a 3 way AOM(auto/off/manual) switch I "hid" under the dash. I hooked a wire to the manual and ran it to the passanger side kickpanel. Then used the Littefuse Mini Add-a-Circuit and hooked it to a fuse that came on and off with the ignition. The auto part I will hook to the a/c when I found a good place to connect too. The reason I used the AOM switch so even if my a/c is off I can still run my fan with the key on. Just something I felt like doing incase the truck would overheat.
Tips:
Use GOOD connections. If you can solder and use heat shrink tubing. You dont want your connections coming undone and/or not contacting well during the summer and causing your fans to go out. Use wire loom to make the setup cleaner looking and to protect the wiring.
