I want to hide this junction box as I have the aeria HSF hydration system and the junction box no longer fits under the stem. Can I get a few of the other type of junctions and hide them inside the aero bars?
edit. Can I use a bar end junction and daisy chain a few of the 4 port junctions (EW-JC304) inside the aero bars?

Could you use a small foam/other material block under the stem to buy a few mm then put under?
I have see someone get the headset spacer junction box mount to drop it lower. That might be the solution.
The junction box doesn’t fit into bars.
You might be able to hide a lot of it in a stem. I’ve done something similar on an old bike with one of the Bontrager Pro stems. I used the blender Mount and had the wires go into it. Though I had the 3 hole junction box not the 5.
Also look at the old Pro Tharsis stem. It was for the older Di2 MTB system.
