The diagram for the Atlas DB9 (and RJ-11) connector(s) are in the "Orion Atlas EQ-G Equatorial Mount" manual, which I think is also online. It shows the DB9 going to a DB9/RJ-12 cable in that diagram which is wrong for the Atlas/SynScan combo, but you can still identify the DB9 signals.
There is no (correct) diagram for the actual cable itself, but I mapped mine out with a continuity tester. It's clearly wrong since nothing is connected to one of the data lines. I will repeat that procedure with the replacement, in case I need to eventually replace it too (with a homemade one). Maybe when I next talk to tech support they can point me to the missing wiring diagram for the cable.
Both manuals come with the Atlas EQ-G.

Orion customer service was very responsive in getting this problem fixed.

Soldered db9s almost never fail unless you are a sloppy solderer. Crimp ones suffer the same malady as the rj45s except one doesn't have to worry so much about springy fingers.
Glad you got things working.

Toss your old worn out connector tools & invest in an AMP. I've have mine set (RJ-11, 45, & DB pin) for 20+ years & have made literally 1000's of crimps. Perfect every time. It ain't cheap (+$65) but it just works. I've have to replace the dies for the RJ45 once.
