Bad news big repair

I wish it used ambient air, when using the block heater the manifold heat shuts off.
Not Nice when -20ºF as she won't fire and run without the heater,
have to open the hood and unplug the sensor to get the manifold heat to work.

Hmm, about this issue. The sell plug in thermostats to be used as 'heat out in the house' warnings. House gets below 40f and it activates the switch. Plug anything into this t-stat switch to turn on as a warning. Can't you use one of these for you block heater?
It's nice when you can keep you tractor functioning as per factory but when too many sensors and computers are used for simple tasks, it's time to go old school and rely on yourself, not a sensor

I think in earlier posts Hay Dude says no electricity available so no block heater normally used.

The ECU reads the air and water temp sensors and they are both part of the glow plug wiring circuit and it has been stated that if the relays are bypassed, the tractor derates itself.
So how do you bypass all that and “simply install a switch”?

Does the tractor possess a derate bypass itself like on a Cummins engine downstream of the other sensors?
Did they hook up a code reader by any chance?
