Drjeseuss built a PicKit2 clone:
After completing the build, I programmed the PIC18F2550 with the PicKit2 firmware using a JDM pin wiggler. I connected to the PicKit2 Clone using both the MPLab IDE, and the dedicated PicKit2 application. Both connected to the unit properly. I loaded up the bootloader hex for the BPv4.0c. I then connected the PK2 to my BPv4.0c through the ICSP header and programmed the bootloader. It worked on the first try! Success!
