I’ve been able to get my hands on some of the older 7970 Di2 stuff since everyone is making way for the new 9070 stuff.
I want to know if it’s possible to plug the Sprinter shifter (SW-7972) straight into the EW-79A-I harness, or would I need to do a little splicing. I’m looking to be able to control my rear derailleur without having to get the special TT/tri brake levers.
If there’s already a post for this, please forgive me, but I wasn’t able to find it.
If you have already done something similar to what I’m thinking, please feel free to share it along with any pictures to detail your progress.
