I take it you don't offroad? If you do, and hit deep water much, get a fan with an even number of blades so if you break one you can balance the fan again by breaking the opposing blade.
It's really not that hard. If you use the Jusnes kit there's pieces to fasten the fan to the radiator -- which I personally disagree with as it minimizes the cooled area. A fan should be mounted in a shroud to pull air through the entire radiator -- but most folks don't go to the trouble even though it's well worth it.
But your question was electrical and i digress, lol
-- you need a connection directly to the battery, fused near the battery to protect the wiring. That power is for the fan motor.
You need "switched" power and the easiest way to pick up that is from the cruise control servo if you have cruise. If you don't, you probably need to run a wire in from the cab. You can pick up the radios yellow/black wire for that for instance.
Finally, you need it to run when your AC is on. I have mine connected to the AC compressor wire in the engine compartment, but that means the fan cycles a lot. Personally I prefer it that way, but it bugs some folks and a case could be made for wearing out the fan I suppose. The alternative is to run a wire from the purple lead on your heater controls in the cab. That wire goes hot to tell the PCM to start cycling the compressor clutch whenever AC is required by the controls. It comes on and stays on.
If you search you can probably find some posts about hooking it up. It's really not that hard. Probably the hardest thing is getting your old fan OFF the waterpump pulley, lol.
