Adam,
It is a fairly straight forward installation in most cases, but the application will vary with the location. I am not sure where you intend to mount the unit, but I mounted the one in my 2000 Marquis, next to the transfer switch on the celling of the basement. The downside to that location is that you can not see the indicators on it unless you are in the basement.
The only installation tip that I can give you for all locations is that if you use very flexible automotive type wiring for the connector cable, it is much easier than using the stiff household type wiring. However, either one will work.
