Just thinking the temp sensors for gauge & ECU are separate :-S .
gauge is single wire & ecu twin wire plug.
ICP does do both the sensors should you need them & no more than £10 each
Ideally you want do fault codes, check basics of dizzy cap, arm. ht leads. coil & engine earthing related to starting/cutout & check/change thermostat & fill coolant correctly & use car a bit & keep eye on things.
If you have some fault codes it could help but worth resetting & then reading again to see what comes up again thus recent problem.
Hold off buying too many parts at moment as best waiting for better diagnosis or more obvious symptoms to arise.
