Sorry about that, I mean to make sure your connector for the fan assembly is fully inserted, since I have heard a few of the connectors being different than original design, as far as the out side ambient temp sensor located in the drivers side lower grille it can very quite a bit and will change and adjust itself as you drive the car, but should not be a large amount of variance afterwards. I do think it does have some reference to the engine ecm such as a/c request and such, I'm sure some one will chime in who knows more about it than I do. Hope this helps.
