What do you mean?
Do you mean you are designing a board containing a PIC18F14K50, and need to allow for debugging,
or that you already have the board, and want to know how to attach the ICD to it?

... assemble a programming adapter ...

What? You either need the RJ-style connector on the PIC18 side - - - or just 6 plain pins in a single row (the "PICkit style"). For the latter, adapters from RJ to 0.1" and 0.05" are readily available from Microchip. Hardly worth to create your own adapter.
(The 0.1" single-row approach is my personal favorite: applicable on breadboards and PCBs, robust, simple, useable with pogo pins.)

PEBKAC / EBKAC / POBCAK / PICNIC (eventually see en.wikipedia.org)

One of the problems with this chip is that PGC/PGD are also the USB pins. So make an adapter that plugs onto the USB connector with a flying lead that you can connect to the MCLR pin somehow.

Programming and/or debugging the 18F14K50 is a pain. Check out the limitations in the programming document http://ww1.microchip.com/downloads/en/DeviceDoc/41342E.pdf
 
There are two adapters available... AC164114 for programming and AC244023 for debugging.
Finding info on these is difficult searching the main site, but they show up on MicrochipDirect
 
If you can, I'd suggest using the 18F24K50 instead. It's a nicer chip and nothing special required.

Good luck with that... I don't see the documents online so try asking Microchip.
 
For AC164114 (PIC18F1xK50 Programming Adapter) you're looking for document DS51887A
 
For the AC244023 debugging adapter (Processor Extension Pak for PIC18F1xK50),
from what I remember you have to have a DIP20 socket on your target board.
The AC244023 has a special -ICD version of the device and it plugs into that socket, taking the place of your device.
 
I made the mistake of using the 14K50 once. Never again... it's not worth the hassle.

I think you are looking for this document ...
http://ww1.microchip.com/downloads/en/devicedoc/50001292w.pdf
 
It seems to have changed document numbers. Scroll well down it for the info you want.
 
The adapter is here ...
