In Pins.h, the three thermistor pins for RAMPS are named TEMP_0_PIN, TEMP_1_PIN and TEMP_BED_PIN, respectively. This is a bit confusing as the board has them labelled as T0, T1 and T2.
TEMP_0_PIN = T0 on board = pin 13.
TEMP_BED_PIN = T1 on board = pin 14.
TEMP_1_PIN = T2 on board = pin 15.
If you change the following line:
#define TEMP_0_PIN 13 // ANALOG NUMBERING
to
#define TEMP_0_PIN 15 // ANALOG NUMBERING
in Pins.h, you should be good to go. This is about line 630 in the file (in the version I have, which is fairly recent).
There's a little guesswork involved in the above, so please test and let us know how you get on.
