Dual Contour efan install
I had all this info in the 'Taurus fan install' post, but I thought I would post it here under a correct title to make it easier to find for anyone looking.
94--2000 Ford Contour or Mercury Mystique with the 2.5l 24 valve v6 engine.
Reputedly it moves 3400 cfm.
I did this entire install for just under $70, but I already had the Thermo. controller. (under $20 at any a. parts store)
Quick connect 'plug' to save $.
Completed wiring system
Ford Taurus relays from 90's Taurus with 3.8L:

Bonk! forgot the schematic!
I haven't really had any road time with it yet because my cheapo Sunpro temp gauge went out before the project started. Second one in two years. I just installed an electric Equuis (sp?) gauge, and of course I messed up the sender when I installed it!
I got to have a temp gauge to drive!
Also, the shroud was hanging from the top alone, and so it could vibrate and rattle at the bottom, so I welded up a couple of braces, and riveted a piece of aluminum stock into the oem supports. Here is a photo.

looks like when the key is off the fan is off .so the new cars have the fans run off the hot so that they can run untill the temp is satisfied help cooling the system off,....well just saying,,.. anyway just thought what if a hand-off-auto switch was in the cab just in case the probe malfunction and it is only a few more wires to the relays so they can be of a light gauge also,just my two cents, looking good

With your system you can wire it any way you want. That's the beauty of buying/building your own. What you see is how I wanted mine.

In the schematic, the 'LED' lines are to dash lights that tell me if the fans are running. If you want the fans to run when the key is off, then run the controller + to the battery.

No offense taken. I'm glad you pointed that out. You allowed me to clarify it for others who may be wondering the same thing.

Did you use 12 or 10 gauge wire for the 12v positive? And what's the bright green thing between the relays? In your schematic you have two 30 amp fuses (one for each 12v hot) coming from the battery but in the pic it looks like only one circuit breaker. I may end up going with electric fans so I just wanted to make sure I'm clear on the wiring.
Thanks!
Thanks!

I used two 12 ga. wires to batt., one to each relay.

I have an interesting problem since I did the conversion, and I wonder if you guys could help me out. Before I had the adjustable thermo control, with the radiator probe, mounted beside the radiator with the with the tube to the probe coiled up right there, and it worked great.
During the install I moved it up by the firewall, and ran the tube along the fender to the radiator. Now it doesn't shut off so easily as before. I wonder if the tube is picking up the heat from the header. I mean it is prob. 10" away, but could that affect it at a stop?
