Adapting Glowplug Controller for Grid Heaters

After scouring the TDR, it seems the grid heaters are controlled by a PCM.

My truck glowplug controller works really well; it's fed a signal from a cylinder head water temp. sensor and also a glowplug inhibit switch that directly reads the cylinder head's latent heat.

I'm thinking about using the Dodge grid heater relays and connecting their trigger grounds to my GP controller.

The question mark is the IAT sensor and whether it would be suitable to signal the GP controller.

Any ideas will be much appreciated.

Would it be easier to attempt adapting a PCM?
