Microchip's ICD2 provides a 6 wire pigtail to program and debug PICs. This instructable shows you the pin-out for connecting this pigtail to an RJ45 female connector.

Step 1: Materials

1 - RJ 45 Female Head.
1 - Length of CAT5, ideally with a solid (not stranded) copper core.

Step 2: Pin-Out Table

A neat trick that I've seen used (and used myself!) is to solder the wires to a 0.1" breakaway male pin header ( http://littlebirdelectronics.com/products/break-away-headers-straight ).

good ,which is used software and plz. give the details of programs transfers process? which is ic supported

Its a very good idea but the connector on the ICD2 unit is actually a RJ12 (same as US telephone connector but all 6 conductors) An easy (and cheap) solution for connectors with the ICD2 unit is to make a 10 Pin IDC cable (5pins x2 rows) with the RJ12 on the other side. IDC headers fit on Strip-boards better than RJ12 sockets. If you recycle a lot of old components like me then you find it harder to get RJ12 sockets with all 6 pins at times. where as ICD headers are a plenty, you can pull them off almost anything.

my IDC ICD2 cable pinout is as follows if your interested:
(as if looking at the header on a target board)
Pin Function
[1 2] = PGC
[3 4] = PGD
[5 6] = GND
[7 8] = Vcc
[9 10] = Vpp/MCLR

All my boards have this connector added.
