Product review (2 stars): instuctions written by 3rd party who knows not what they speak of !
Although  the product did do the job I intended it for the directions where so confusing that I read them at least 10 times compared to the factory wiring diagram finally gave up and guessed what they where trying to say ! Fortunately it worked out otherwise could have been a disaster! This coming from a professional repair technician who has been replacing parts and reading schematics for over 40 years order at your own peril
