Working when removed to install a Volvo digital gauge. 

The gauge is standard Teleflex black with white and blue markings, p/n 30742. This was removed from an inside steering station, so it has never been in the direct sun or rain. 

The sender / computer is a Volvo Penta 857448. It goes between this gauge and your factory wire harness. 

Please check your manual for compatibility. This was removed from a 1993 Volvo Penta DP-C outdrive.
