>>1678110>>1678111Yeah, that's pretty fishy for $350. It's probably either fucked like anon said or it was stolen and flipped. It looks like it has Shimano Ultegra di2 6870 parts on it (besides the crank). You described the wiring setup pretty much spot on, but here's a diagram as well. You'll need SM-BCR2 (which will connect to junction A) to charge the system as well as connect it to your computer to update firmware and stuff.
