Q: i have a 94 pace arrow in need of this item , I am a pretty good diy guy , is it a hard or unsafe replacement job? thanks

Not unsafe as long as the generator isn't running and you don't have the coach plugged into the wall. I just labeled the old wires and took a couple photos of it before taking it apart to make sure I didn't mix the feeds up and then the install took less than an hour so it should be pretty straight forward as long as you are able to get to the area easily. Good Luck :)
