Classic Instruments Electric Speedo Drive (CISN16F)

16 Pulse Generator Ford SN16 & SN17

For Ford Transmissions w/speedo cable drives

(requires driven gear)

If you plan on using an early Ford-O-Matic, please contact Classic Instruments for speedometer sending unit options.  Early Ford-O-Matics have a specific speedometer cable connection that requires a separate special adapter.

Some Mopar transmissions do not have a speedometer cable output.  If you plan on using a Mopar transmission, check the rear of the transmission for a speedometer cable connection where a standard sending unit will thread on.  If none is present, please contact our tech department for other speedometer sender options.”
