If I were to make up an extension using CAT5/6, I would use one pair for
PGD, another for PGC, and the other two for VCC5, tying the four returns
of each pair together and wiring it to Ground. I'm taking it for granted
that MCLR is really unused.

A little info for those wanting to make longer cables
As I understand it the Elecraft connector is a Modified MPLAB IDC 2 In-Circut
Programming connector
Here are the pin outs as I read them
1 Unused - MCLR, Low to reset CPU
2 +5 vDC - VCC5
3 Ground - VSS
4 Data - PGD
5 Clock - PGC
6 +5 vDC - VCC5
