Just yesterday I hooked the Picstart Plus into my system as an ISP.

I am using 16F84s and all I did is run wires from MCLR,VSS,RB6,RB7,and
VDD.  Then you need to attach these wires directly to your circuit.  Then,
you
should add a pullup to your real VDD.  I used a 470 ohm resistor.  Then you
should also add a 470 ohm resistor and a diode (I used a schottky)  from
VDD to MCLR with the cathode at MCLR.

Then press program on the Picstart Plus and everything works wonderfully.
I was also impressed with the rev 3.40 of MPLAB.  This and the new Rev1.5
firmware for the PicStart hardware, realizes quite a downloading speed
increase.

If you want more information, go on their website http://www.microchip.com
and get
the PDF on ISP.  It explains the connections and methodology for the other
PIC
devices.
