How do I wire these up? Do I need to remove all these bottom screws in the third pic? I also see what looks like a small access hole in last photo. The front shifter has a rubber plug for this hole. Is that cable routing access?

I haven’t found instructions online. Not sure what to even call these. Whenever I google l get different models. I bought them on eBay and the plan is to do an upright conversion on a road bike equipped with a standard Shimano 10-speed cassette and 10-speed Ultegra RD. In the front is a FSA compact crank and I assume an Ultegra FD.
