You seem to have everything figured out for the most part, but you do need another SM-JC41 to connect everything up at your bottom bracket.
Concerning wiring you could go for a Y-cable for your handlebars, using the EW-JC130-SM(or the -MM if you go for some wide bars). The 450mm goes into the left shifter, 50mm into the right shifter and 350mm into your EW-RS910.
From there on you'll need a (long)cable from the EW-RS910 to (around) your bottom bracket into the SM-JC41. Depending on framesize a 1200mm would be nice.
And then a cable from your R8050 to the SM-JC41, I guess something like 700mm to be safe.
Of course another cable from SM-JC41 to EW-WU111. And one from EW-WU111 to BT-DN110-1. Both around 400mm.
To sum it up:
1x EW-JC130-SM
1x EW-SD50 1200mm
1x SM-JC41
1x EW-SD50 700mm
2x EW-SD50 400mmHope it helps :)

Could you help me?
Just wish to check on the parts I still need to order for my Di2 groupset and you seem good at reading the Shimano flow charts which make my head meltdown
Currently I have bought or have on order
DA 9170 shifters and brake callipers
Power2max rotor 3d cranks
SM-RT800 disc rotors
R8050 front mech
R8050 rear mech (medium cage)
CS HG800 11-34 cassette
6700 Ultegra Di2 Front Derailleur Band adapter
I wish to use 3t Aeronova bars with the bar end port
On my still to buy list are
EW-WU111 di2 ant bluetooth unit
BT-DN110-1 battery
EW-RS910 bar end port
grommets
cables
Does this seem correct?
Which cables should i be buying to configure all these items? cable length through bike to be confirmed by @coldharbour, but guidance on which sorts of cables (Y etc) would be great
I already have the charger from R785 groupset.
I think I will have to mount the battery inside a thomson seat post with packing foam and sticky tape.
