I've got SW r9150 climbing shifters which apparently don't need a 'brain' to connect into ie into the shifters. Someone on slowtwitch just connected directly into a 5 port junction box.
Yeah, they'd work the same as the TT shifters. You just plug them into a 5-port alongside the normal shifters (or a 3-ports if you don't have normal shifters, ie. TT bike).
