Easy to wire in. Instructions in the box. As far as taking the old on off im assuming since yours is a 82" it has a mechanical fan running off the motor. Also easy, just take off bolts, but you shouldnt have to there is enough space that you can install the electric without having it interfere with the stock one. You will have to remove the radiator to install the electric fan.There are plastic ties that pass through the radiator fins that are a bitch to install without taking out the radiator. I have the electric running in conjunction with a flex fan and it works real good.I paid about 60 bucks for mine locally at the parts store. It was called a Slimline. By the way I replaced my fan shrould with a half moon chrome one.This caused part of my overheating problem,if yours is stock you will have more work to make it fit ,I think.This is all based on the many hours under the hood of my 86" Hope it helps.
