91 ALDL pinout.
Can anyone tell me which pin provides serial data on my 91 L98. I'm hoping to get Tunerpro running for any future diagnostics that are required. I'm in the UK so expertise is not easy to find.
I have an FT232 USB - Serial converter and an ALDL plug which only appears to be wired to pin M ( 8192 baud )
Any advice much appreciated ( I have searched but not found the answer anywhere )
