Microchip has a 8pin ICD header you can purchase from Mouser. If I remember right it was $30+, and I didn't use it very much in the project. The header has the ICD connector and a PIC on top, and a 8pin header underneath that you can plug into the DIP socket in your circuit. MicroChip has documentation on this part in a pdf about their development tools, and it will allow you to debug the 12F629/675.

A special 14-pin PIC12F675-ICD device is used with MPLAB ICD 2 to provide separate clock, data and MCLR pins and frees all normally available pins to the user. This special ICD device is mounted on the top of the header and its signals are routed to the MPLAB ICD 2 connector. On the bottom of the header is an 8-pin socket that plugs into the user=E2=80=99s target via the 8-pin stand-off connector. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
