For those people who wish to retain their old gauges and speed-o meter, Flat-o Products, Inc. offers a short jumper cable that allows you to connect to your OEM speed-o meter cable. Our Speed-o cable also has the proper end for the C-4 trans, which makes it very easy if you need to add a ratio adapter (pictured) for calibrating purposes.
These cables as well as custom made cables always available.
