Good day together, I changed the lock of my tailgate today, which is however manual i.e. only with softclose, that is nice, but I noticed the red switch on my tailgate. After turning off the panel I could see that the red switch is connected with an electric cable, the switch however cannot be pressed, that is clear to me, because it is not an electric tailgate. Now to my question: if already switches and electric cables are available anyway And if so, what else do I need to be able to upgrade the tailgate, or can you do it yourself and how? Best regards and I am very grateful to you. Thank you.
