Everything works great! They automatically activate when the doors open and close. All the parts you need are here, I just took them off my Toyota Tacoma recently and replaced them. Here is the link to the original product: https://ampstep.com/products/amp-research-powerstep%E2%84%A2-75142-01a
I took them off because they are a bit noisy when they go up and down and have some scuffs on them, but other than that they work perfectly. Feel free to reach out with any questions, asking for $600 OBO.
