Mate, had a look at the wires from the tail gate to the body of the cruiser and could not see any problem. While feeling the cluster of wires however, the auto locking was being triggered so I cut open the protective case around a group of 5 wires (down near the hinge on the tail gate). Upon opening the protective casing (tape) I found 3 of the 5 wire were broken completely and the last 2 badly damaged. I now just need to rejoin these wires and the problem will be resolved.
Thanks very much, your advice saved me hundreds of $ had I used the local auto electricain. WELL DONE.
All great thanks mate....top marks.
