G - Then follow the wire through the bike and untighten the deferent fastening point, and get the all thing removed from the bike. (pay close attention of the cable routing for the new one!)
(the hard part is going through the plastic cover inside the frame. For this I’ve removed the 1 screw easily accessible, and then bend it to get the cable to go through. Removing the all part looks pretty complicate, and might involve a lot of disassembly!)
Here is it!
H - Then install the new module using the same routing for the cable, and plug all 3 connectors!
Reassemble everything! You’re good to go!
Let me know if you have question or if you do the same, just put a picture on
