Poor engineering but woks
When in the first step it tells you to pull everything apart and wire everything up to see if it functions make sure you do that. The motors were wired possibly backwards or on the wrong side of the lowering arms swapping things around I made it work but it's still not perfect. now the motors are on the front side of the lowering arm but it to goes in the correct direction. passenger side rear door and the driver side rear door sensors had to be swapped. they were labeled wrong.
