I purchased the kit from hunter prestige UK. Their video is very straightforward. Took me about 30 minutes to complete. Works perfectly. Hardest part is fishing the power wire out of the rubber tube. I wish they provided a factory pin for the fuse box but what they provided works fine also. I used factory Tesa cloth tape (available from Amazon) to wrap the harness. Looks completely factory.

 

Great job.

I know everyone (including me at one point) has said how utterly useless the rear door soft close is... but I admit there has been a time or two where I've had bags in hand, a dog on leash, etc where it has grabbed and secured the door whereas otherwise it would not have closed. So I like the modification!
