Don't bother with crossover.

Gigabit doesn't need it, and most switches are auto crossover anyhow
even for 100Mbit.

Certainly inside the wall pin1 should go to pin1.  Don't hide crossovers
in the wall.  Just run all the wires stright from one jack to another in
the wall with the same pins matching at each end and it should all work.
