i will post if you really want, but the two main things are these lines:
\\these change your board to recognize it has two hotends and a heated bed rather than a hotend, a fan and a bed
#ifndef MOTHERBOARD
#define MOTHERBOARD BOARD_RAMPS_14_EEB
\\simple stating you have two hooked up
#define EXTRUDERS 2
\\the distance between your two nozzles, in my case its 30 mm on the x axis, the first extruder is 0,0
#define HOTEND_OFFSET_X {0.0, 30.00
and dont forget your thermister for your second hotend

Hi, I put four extruders with ramps 1.4 without adding steppers. With my marlin and a card to 8 relays can control up to four extruders with only two drivers.
Otherwise you can mount another external driver taking three free pins to control it.
