I thought I would post my new Cervelo P2 setup for anyone who is trying to do something similar. My recent broken shoulder has given me a little time to play around with my new aerobars. I learned a lot from other posts here on ST. Here's the build, routing, and photos. Feel free to ask questions. Thanks!

Zipp Vuka Stealth Aerobar Setup
Shimano Ultegra R671 Di2 bar end shifters
Shimano 9071 Di2 brake levers/shifters
2x Shimano SM-JC41 internal junction boxes (stuffed inside base bar)
2x E-Tube wires to connect the to bar end shifters to internal junction boxes
1x E-Tube wire to connect the to internal junction boxes together
Bike Setup
Shimano Ultegra 6870 front derailleur
Shimano Ultegra 6870 rear derailleur
1x Shimano SM-JC41 internal junction box (stuffed inside seat tube by bottom bracket)
1x E-Tube wire to connect junction box from base bar to seat tube port
Seat Tube/Post Setup
Shimano EWW01 D-Fly
Shimano SM-BTR2 internal battery
Shimano SM-SW90B 5-port external junction box
1x Shimano SM-JC41 internal junction box
1x E-Tube wire from internal junction box to one near bottom bracket
1x E-Tube wire to connect battery to internal junction box
1x E-Tube wire to connect D-Fly to internal junction box
1x E-Tube wire to connect D-Fly to external junction box
Both the front brake cable and Di2 wire are routed through the bottom hole in the base bar.
I was able to route the rear brake housing through the inside of the top tube. I just had to drill out the plastic cable ports by the steerer and seat post. Pushing the cable through took a bit of effort and trial-and-error, but the rear brake feels good.
I had to drill one hole in the seat post for the E-Tube wire. I've mounted the external junction box with zip ties to the seat rails. I really don't need rear hydration this time of year, but zip ties are easy to remove and I can reposition the junction box when needed.
If I really had the spare time, I would draw up a schematic, but tried to provide an accurate overview of the parts needed. I hope this helps!
