As this Patrol was a ZD, it has a heat switch on the dash which puts the revs up on the motor when at idle. Now not used for the TD42. I did have a small rocker switch in the dash I was using as a manual override for the thermo fans for when the kettle boils. I’m now using the defunct heat switch for the thermal override function.
