I have a 1994 Itasca Motorhome with a GM 454 7.5 L TBI  P 30 chassis
My Water Temp Gauge has failed installed new sending unit and thermostat $400. for a new dash unit.
How can I install a after market gauge and sending unit and keep the existing sending unit to interface to the electronic module ?
