In very low temperatures, around 25F or less, the RA and Dec cables start getting a bit stiffer. They still bend but are a bit resistant, like an extension cord or garden hose left out in winter. Periodically it is good to check if they are well seated in their sockets, the Dec motor side wiggled loose on me once and my slews started failing. I also use a small dab of dielectric grease, the same stuff used on auto battery cables, to keep the connections working well. Have used my G11 down to 15F, but that is also my personal limit for being outside at night :).
Also using rubber dust plugs on all the unused Gemini cable ports is a good measure year round, to keep out moisture and frost, etc:
One example:

These don't hurt on the PC side of things as well.
