I am looking at putting my first tt bike together and am planning on using di2.
I am struggling with with the wiring layout, not helped by being in the planning stages and not having the bits to hand.
I really want to use a bar end jct a but think I will need more ports. can I use a second jct b 4 port to join up the sattelite shifters??
does anyone have a wiring diagram to show?? its a cervelo p3 frame so limited opportunity to hide things in the stem

Yes, you can use as many junction Bs as you like - they are basically just 'dumb' four way splitters ;-)
There are wiring diagrams in the dealer manuals on the Shimano site: https://si.shimano.com - basically enter your hardware series in the search box and open any 'DM' (dealer manual).
I have also linked those dealer manuals here: https://bettershifting.com/di2-for-dummies-beginners-guide-to-di2-manual/#shimanomanualsandotherresources ;-)
(also, the slowtwitch forum is a good place to start for TT setup help)I run BetterShifting.com - Di2 help / tips / guides1 -
