After market central lock?

I bought this after market central lock and got it installed, but there seems to be a problem with the mechanism. The locks engage well when the driver side lock is engaged but then I'm unable to pull them up. When this happens the controller gets too hot.http://s29.postimg.org/dloqn8s07/Capture2.pnghttp://s22.postimg.org/gqdsdk2bl/Capture.png
