I looked, but my concern is that this is a SMD component soldered to a board
that is constantly powered.  Can't remove the power (you can, but it's a
severe PITA).


I used a wire wrap to my PIC 16F873A. No problems.

Check the polarity?   Which polarity are you speaking of?  It sounds like
you are talking about the power that goes to the ICD from the 9V adapter.

the ICD2 to the PIC. For starters the PIC should be

What if I can't isolate the PIC?

Use MPLAB to connect to the PIC using the ICD2 as a
