This retrofit is proving to be tricky so I wouldn't recommend it to the novice even if you get the kufatec loom.
First of all, the loom doesn't cater for parking aid. It is briefly discussed in this thread but I thought I'd mention that it is a useful feature in case you try to accidentally open the tailgate with another car behind you. We're past this part of the install and parking aid is now integrated using the standard schematic and a relay.
Secondly, the lower studs (which used to be upper studs before the retrofit) are snapping out from drives. This is quite dangerous in case both of them snap out and there is somebody under the tailgate.
I am going to order another pair of 7E5827439's to fit as the bottom studs onto the custom made bracket.
Also, I have had to make a longer cut in the tailgate (will post pics later).
Another thing, which was not mentioned on this thread is the fact that I will need a new remote key that has a tailgate button. Apparently you can not use the original keys from a non-motorized tailgate car to open the converted tailgate?
Here's a pic of my key:
Besides everything, I think there is something wrong with the drives after they snapped out couple of times: they produce very loud noise when operating and I guess I will need to take them apart to see what's going on.
@Robert any tips on what to look out for? (I know you took them apart as was shown on the video)
And finally, there are couple of additional parts which I suggest
@Robert to add to the original required parts list:
1 x rubber seal at the top. I don't yet know the part number for it. Trying to find out.
2 x countersink bolts for the custom brackets. These can be reused from the original tailagate latch which you won't need if you install a tailgate soft close due to replacing them to longer bolts:
Any ideas are welcome at this stage.
