Got my Amp power steps installed this weekend. Took about 7 hours over 2 days. Had some issues with the instructions (color blind) person wrote them. Had me searching for dark gray wire, when in fact it was light gray.
Other than the wire issue, it was fairly easy. Time consuming as Me nor my friend (who is a GM Master Technician) had a clue.
We had two panel retainers that were smashed from the factory when we took the front door panels off (replaced them on re install).
Overall, I'm extremely pleased. I'll put up some pics, soon.
