Cable Attachment Point on Shimano 600 FD?
I'm replacing the shift cable on my M2 Pro Specialized that has a Shimano 600 FD.
The old cable was attached on the top left side of the bolt, however, there seems to be a clear cable guide groove on the lower right side.
Which is right?

IME the cable is meant to pass over the bolt, as in the picture.
Perhaps the groove is either for changing the derailleur's ratio for some unclear purpose, or to assist with routing the cable as I do on all FDs - all the way around the bolt for tidiness.
But the way that groove sits, following it would mean a loop above the bolt, which isn't tidy, so I guess the former.
Just do it like this for the win ; )

That model was unusual, it had two grooves to accomodate both STI and downtube shifters. If you're using downtube shifters or bar-cons, use the routing shown in your photo. If you're using STI, use the other groove.

Isn't one side for Dura-Ace shifters and the other side for all other shifters?

Oooh if we could get a definitive answer that'd be awesome because I'm using downtube with these right now, but will be getting the STI levers soon to upgrade.

Bottom line, it has two different actuation ratios. So if you wire it one way and the FD doesn't move outboard far enough to center up on the big chainring when you shift, then you need to wire it the other way 
And vice versa.
And vice versa.

I have STI shifters. I wired it the same way that it was, and it works fine. Thanks for the help.

I have bar end shifters and mine is routed the same way as yours. It works, so I'm going to follow dsbrantjr's advice leave it alone. It would be nice to have a definitive answer, though.

I rummaged among our old Shimano tech manuals, but they don't go back quite far enough to cover that version. With non-indexed shifters, there's really no "wrong" way as long as your shifter's not running out of travel before reaching the big ring.
