Hm, well the pin is connected to a "power good" signal. But it's not some signal coming from a chip, it's just a signal that will be given by some transistor logic on the power supply board. I guess I could pull it low with 2k and make it active high, that would be easier than a jumper. That would work, right?

(It seems this is not in Microchip's ICSP Guide, but >of course I could have missed it.) The reason I suggested the resistor is to keep from having to short it. All you really want to do is not let the LVP pin float during the probably brief durations that the config memories are erased and the LVP pin is on. 33k has a neglible impact on any digital I/O function but will keep the pin grounded during programming.
