[dwag]

Need help troubleshooting eng temp gauge. Gauge stays @ half range eng cold or hot. wiring good, sender has 2 wires on it which none of parts books show. No ohm reading across wires on disconnected sender. whatsayU, john

Sender in the thermostat housing area with 2 wires is for the injection pump cold start function.

Sender for gauge is one wire and located at the top left rear of the cylinder head.
