I aquired an older Accel dfi, Professional Racer Series (with the billet Al Case and Aircraft connectors); model 01423/01424, 100592, s/n 003729. It came with a very nice harness, but with no manual. Can anyone help me with a copy of the manual, or more importantly, with the connector pin out information. There are two round connectors, with the pin location designated by letters, A, B, C, etc. A pre thank you very much if any GNer can help.
