PICkit 2 or PICkit 3 connector clarifies the purpose of SK9 connector on Velleman K8055N board. Comparing SK9 connector to PICkit 2 or PICkit 3 connector reveals that all the signals on SK9 are arranged in the same order as on the PICkits. The original K8055N experiment board on the photo bellow only has empty holes, where you can solder a 5-pin male single inline connector (SK9) that enables a direct connection to a PICkit. According to K8055N documentation it is also obvious that PICkit 2 and PICkit 3 can easily do in-circuit debugging and programming with K8055N. Therefore K8055N can serve as both programming header and experiment board for PIC18F2xJ50 microcontrollers. Any low voltage programmable microcontroller that you can use with K8055N board can also be programmed/debugged on K8055N board with PICkit 2 or PICkit 3.

Here are the necessary connections to PICkit 2 or PICkit 3:
SK9 - pin 1 à MCLR (PICkit 2/3 pin 1)
SK9 - pin 2 à Vdd from target (PICkit 2/3 pin 2 = +3.3 V from the K8055N onboard voltage regulator)
SK9 - pin 3 à GND (PICkit 2/3 pin 3, ground)
SK9 - pin 4 à PGD (PICkit 2/3 pin 4, program data)
SK9 - pin 5 à PGC (PICkit 2/3 pin 5, program clock)
NOTE: PICkit 2/3 pin 6 (PGM) is not used for PIC18F2xJ50 programming and it should not be connected.
