Any thoughts on the used controler that I bought? Should it act just the same as the one in the car or is there something that needs to be done to it to get it to work.

I need to know because if there is something wrong with it I can return it, if it is ok and just needs to be programed or something it wouldn't seem right to return it because I needed a test part.

The left front sensor was replaced not that long ago because the speedo needle was jumping, that took care of that problem. And since he tested the rt front and said the signal was good why would the controler spit out a bad rt front sensor if it's the brake light switch?
