It'd be GREAT if Microchip included this stuff in their datasheets. I pulled something from one of their eval boards and have used it in several 18F based products. Here's what I use: MCLR pin goes through 470 ohms and 220nF ceramic to ground. MCLR has 10k pull-up to Vcc. On a 2x5 header, pins are connected as follows: 1 - MCLR 2 - Vcc 3 - ground 4 - PgD (RB7) 5 - PgC (RB6) I have little adapter cables that have a ribbon cable spliced to the RJ45 (that's it, isn't it?) that plugs into the ICD-2. Additional pins on the 2x5 header handle I/O required on the product. This has been used on several 18F products and there are now thousands in the field. Seems to work...
