This is a pretty common e-fan swap with lots of info out there: Here is some of the material that I accumulated when I did my swap. Also included are a few installed pics. I went whole hog with the relay kit and put in the 175 and 195 temp senders and wired it to my A/C system. Comes on when water temp rises to 175 on low speed and steps to high when temp is 195. Also steps to high when the A/C is turned on. I put in a 160 degree thermostat as well.
I know you asked for a basic install, but there is ample info on these sites and others that will undoubtedly be referenced by other board members.
