I have 2 AVR programmers and after a lot of trial and error, I realised that the pinout is different for each of them. Also, the datasheets for both the programmers are hopelessly unclear and show the pinout for the pins on the programmer. When you plug in a ribbon cable and turn it around to face you, the pin configuration becomes a mirror image and it’s quite taxing on the brain to correlate the pin config from the board to the cable. Hence the images below for reference!
