Electric fan question......

I want my electric fan hard wired on high. I have used a solenoid in the past with great results, but somehow ogt my wiring wrong. Anybody know the wiring for this. One ground from fan and the high speed wire from fan, then where to from there?

I am not looking for answers about fan controllers. I am looking for the answer to my simple question......well, not simple for this boy today.

Here is the diagram to the fan setup I've built and am getting ready to install on my car.  The diagram calls for 2 relays, 1 5-pin and 1 4-pin, but 2 5-pin would be just fine.  I'm fused for 60A and I'm running all 10GA wiring except for the relay signal wires.  The fan came from a 2010 Fusion and fits our radiators almost perfect.  I removed the variable speed controller and built out the relays to do a similar job.  I use a blower resistor to lower the current and by proxy, the fan speed.  The resistor will burn up if it's not secured to the fan in the airflow path, so mine is attached in the former speed controller location, I also happened to have a connector for it, so it's nice and neat. I'm considering reversing the current flow through it to avoid blowing the thermal limiter. 
The beauty is: the fan can be running low for AC, and then kick up to full for a high temp condition if need be, and the transition is seamless, it doesn't even matter if the low relay is on, because once the 2 speed relay kicks on, it doesn't have to care what the other relay is doing.

Just got your last post. I hooked up the fan as the diagram in my post showed. Just as it shows. I have a solenoid (heavy duty), and it still comes on when the power wire to the battery is hooked up. Can't figure it out. It should only come on when the key is turned. I am trying to get it to work. I can't get to the parts store till this evening. The Sport is down.

In the diagram I posted.....it shows a "switch" in the wire to the fused source. I'm wondering what switch they are wanting, or if it goes to the switched source when you turn the key on.

Is it on without the small wires (ground and trigger) connected?  Or is it on when you're connected to your switched power source?  Just one more question, why are you connecting it to come on with the ignition?  You don't really want it running all the time do you?

Yes, I want it running all the time. Like I always have had it.When all wires are connected, and I hook the terminal to the battery, it comes on. It should be off til the key turns it on.

FINALLY!!! I figured it out. The solenoid is brand new.............and a bad one. I installed another solenoid, and now we have a fan again. One day I'll install a new fan kit, but for now, I'm happy.

I appreciate all of your time helping me with this.

Am I the only one that is confused with what Vinnie has been trying to do? For an always-on, a 75A Bosch relay works fine. Connect to battery, ignition wire on the driver side of the engine bay, ground, and run to fan. I don't understand the need for the solenoid? The left side of TheFoeYouKnow's diagram is how it's typically done.
