2012 D40 no power to auto transmission

I'd imagine it's a fuse in the engine bay, probably the black box just behind the battery.
Thanks mate
Checked that a few times over the corse
it seems to be the wires from plugs E6,E7 and E15,E13 in the drivers side engine bay fuse box all the wires to the transmission plug F 36
From transmission memory backup Red 1 and 2 goes to plug E15 blank
4 grey K line goes to orange E7
6 yellow power supply goes to black ground E7 (yep)
7 light green backup goes to blank
9 brown starter relay seem to be correct
And all other wires in the 2 plugs
Ive been using schematics that don't match
Been to a few wreckers to find what goes where and no luck , Spanish models all different
Any help would be appreciated

2012 was part of the transition from the RE5 box to the RE7 so it's no surprise that there are a couple of variations in wiring. This continued until 2015 models, as far as I understand, so if you look at any 2011-2014 V9X model they SHOULD be similar, the YD25s are different and don't even have the E7 connector - but E7 also connects to the electronic throttle actuator (F8 - understandable for TCM control).
These also pass into the IPDM/ER which has a fuse for the TCM. This fuse is inside the IPDM/ER, it's 10A and located beside the cooling fan relay - 2nd from the end nearer the open space (the side with the chamfer).

Thanks for taking time Tony
Makes sense, Thought I was in a parallel universe.All relays and fuses seem good
( 3 auto sparkys, 3 mechanics and 2 gearbox specialist later) I will try sourcing something for a VX9
Im still unsure about the plugs
(E7)yellow one-side of plug black opposite (F8) - grey in orange opposite - light blue in blank opposite, light green in blank opposite
And on the other plug red in and blank opposite
Would it be common for the transmission wires (light blu, red,light green )to come up from transmission to a plug point that is blank on the opposite side , not to mention main power yellow from transmission to black earth that goes to the front near battery

Nissan - as you might think - aren't in the habit of creating all this wiring and not having it go anywhere. Something in there isn't right, I wonder if you can spot any sign of the harness being modified/cut and taped up? Could someone have done this deliberately to cause grief? Maybe they were trying a modification to the car? Or - worse thought - they've put in the harness from a different model?
I'm struggling here too!
My thoughts also , like manual harness, big job ,the harness looks good cant quite read the parn number to check , but im out of ides and think manual harness
I checked the same same model in a 2014 today and yes the colors are to match
unlike my example
I have traced back the harness a couple of hundred mm and no sign of cut wires
I guess they were never there
if I find a schematic to suit I might be able to do something from point a to b and c
It seems to be only 4 wires
Is there anything to my 2 plugs being E6/E7 and not E6/ F7
Like E7 manual and F7 auto
This relay missing on mine mabee reverse lamp ( the other different blue might be spotlights)
Mine is 2 blu 2 blak and 1 light brown

I'd have to go through the wiring diagrams for those plugs, which I can do tomorrow. I've been on the go since 3:30am, I'm calling it a night! I'll leave this thread open to remind me.
Thanks Tony
when you have time , no drama , been a couple of years so far , another week or so all good
