Joying Head Unit in the Toyota 86 GT

[FRS2017]

Well,

I finally got my delivery of my Joying head unit, its been fun and also a bit pissy to get it working and get it flush with dash trim. I am wondering if anyone out there can point me in the right direction on getting it all working:

I have connected all the wires to the harness and only get the backup camera to get working and im facing a strange issue (the backup camera stays on all the time even without being in reverse).

This my current wire config (Please see photos):

I have the accessories wire (camera adapter) connect to the accessories wire on head unit. Then I have the ground (camera adapter) connected the head unit ground. The last Wires the purple wire (camera adapter), which seems to be the white on the diagram I have tried to the reverse trigger wire on the Toyota 86 loom. The back orange (head unit) I have connected to the reverse trigger wire on the loom (Orange and white) if I have got the reverse trigger wire correct???

I think where I am going wrong is the accessories wire (RED) on the camera adapter needs to go to the reverse trigger wire not the head unit so the reverse camera only comes on when the camera is in reverse??? - not sure but brain wave just kicked in lol.
