Electric fan wiring help?

Will someone please point me in the right direction on a kit I can get to wire up my electric fan. I have heard that I will need a thermostatic fan control kit so that I am not just depending on the stock fan switch. I JUST finished rebuilding the head and cooling system and cannot risk overheating
THANKS

nobody has used this?

Here's a bone.... ready? Catch!!!

There's threads here too. My wiring is different. Feel free to ask after you've done some reading up on the subject--

Have fun.

EDIT: The first thing I'd do is get a real water temp gauge. That way you know what is going on at all times. Individual preferences vary- but I use a full-sweep Autometer ES. Accurate, nice looking, and matches BMW illumination. Pricey, but worth it to me.
