Use a bed of nails to get to 5V,GND,MCLR,RB6 and RB7 pads. It isbetter if you supply your 5V from
the PVB itself.
Don't use a PROMaster for in circuit programming. We've had heaps
of shit with earth loops etc with a few different PROMasters with ISP.
It may be a wonderfull programmer, but it was not designed for ISP.

BTW we ended up designing our own programmer for Mchip and
Motorola (It uses an Intel mcu). It solved all our problems.
