Glenn, I just passed this point in the build of my K2 (7418) and didn't have any difficulty.
The instructions on p. 32 specify the length of the four wires as 1.5" and this was more than enough length to properly connect the front panel board to the encoder pony board. With the encoder pony board soldered to the back of the encoder, and the encoder, in turn, bolted to the front panel, the distance between the encoder pony board and the front panel board (also attached to the front panel) is fixed. In other words, the wire length doesn't determine this spacing but needs to be of sufficient length to span this distance. On my front panel assembly, this distance is just under 7/16", a distance easily spanned by a 1.5" wire. Check to see how you're sequencing this part of the assembly; i.e., the four wires don't get soldered to the pony board until this distance is already established by the mechanical assembly. As for the control board to encoder pony board spacing, I agree it appears to be tight. I wasn't aware of the errata Don mentions and, therefore, didn't initially flush trim any of the interference on the control board. Upon initial fit of the control board, the back of the encoder pony board appeared to get hung up on the pins for the U6 socket on the control board. Once I flush trimmed the lower row of those (plus the IC pins on the pony board), there appeared to be adequate clearance. I've completed all resistance checks up to this point as well as the initial power-up without any problems.
