Hi all, so I need some help please. I have had help from previous posts but im now a little stuck and need some help. I have a T5.1 Caravelle, I want to change the rear tailgate to a t6.1, I have the tailgate, and pretty much everything to change it over. I have the last bit I need help with before I change over, I have everything but I've had no luck finding out if I can use the original locking units from my old tail gate for the new one, I bought a new genuine lower catch unit but I need advice about the locking electric control unit, do I need a T 6.1 unit or will my T5.1 unit work ?
