I collect bits that I think will be good for something someday, so I have a 12 pin ALDL plug and a FT232RL chip on an arduino style board. I know the signal line is pin M on the ALDL of the 16197427 BJKW PCM, but I'm not sure just which pin to connect it to on the FT232Rl and what if any other connections will need made. Can anyone help me out here?

I found this on this forum http://www.gearhead-efi.com/Fuel-Inj...USB-ALDL-Cable But it's a 10 year old thread, Robert didn't mention which two connections, the link is dead and Robert hasn't posted for quite a while... Does anyone know what he was talking about?
