UMO hot end thermister

[Pantera09 0]

Greetings,

I have replaced the UMO board with a ramps 1.4 and everything is complete with the exception of the hot end thermistor. on the UMO, there are two thermistors both with three wires, but only two are required for the ramps board. So I can either use the orange yellow and brown or the green peach and tan. My question is, what two wires do I use to connect to H1 Therm,  in what order and what about the third wire?

 

thank you in advance
