They work great....EXTREMELY easy to install.
youll be done in a couple of minutes as long as you are sure you know what all of the wires go to. if you dont know about electronics, ask for help. as long as you have a very slight grasp on electronics this should be a breeze. my only recommendation is to ditch the clips they give you in the package and solder the connections. the clips work fine, but why take the chance of them shaking loose when you can take a couple of extra seconds and do it right and never have to fix it again.
