3T Zefiro cable routing help

Anyone have these bars with mechanical shimano shifters? I’ve been struggling to get them cabled and I’m wondering if anyone here has experience with these bars.

I have them and will probably get rid of them because 7900 doesn’t fit. They were designed for 7800. You may have to go electronic to make it work right.
