Thermostat Housing Wires

I need some help here guys.

I am relocating my coolant temp sensor from the radiator to the top of my thermostat housing where the A/C switch used to be. I am trying to use the Green/Red and Green/Black wires that would have been the two A/C wires and wire them into my coolant temp sensor. I need to know where the Green/Red wire ultimately ends up (I believe in the Fuse Box...upper right relay). I also need to know where the Green/Black wire ends up as well (from my search in the manual...might be the MFI relay)???

I want to cut the ends of these and wire them into the radiator coolant temp sensor so I retain the factory wire routing.

Any help is great...thanks!
