Yeapper, actually you just need 5 pins.

Pick an arrangement - I use power, Vpp, PGD, PGC, Gnd for all my 
designs, just b/c the first ICSP PIC board I made, that's what I did, 
pretty arbitrarily chosen.  Maybe pick an order such that if the cable 
is plugged in backwards it doesn't short though.  (but I haven't blown 
anything up the few times I put the cable on the board backwards.) 
Like... power, PGC, gnd, Vpp, PGD?  not sure.  Maybe having Vpp on a 
programming pin is worse if cable swapped.  Or make a 6-pin and key it.

If you'd rather not cut the microchip original:
H3661R-07-ND
Header that is real convenient!  use this:
S4379-ND

after building and testing a cable, epoxy it.  mark orientation with red 
nail polish or dab of whiteout.

also for low-volume production, where you just need to program once, put 
the 0.1" header pins in the female socket and just hold 'em to the holes 
in the board.  If boards are being contract-assembled, make sure they 
leave the holes clear of solder!  else is a big hassle.

and it is nice to give a cable to clients here and there, to program the 
board you made for them with an ICD2 you told them to buy for updates 
down the road / in the field.

Have fun
