A USB mini to OTG cable will work too, but you must test if the connector fits into the socket or modify it.

# Pinouts
Easylink power/speaker connector:
PIN 2 = Front Left +
PIN 3 = Front Left -
PIN 4 = Rear Left +
PIN 5 = Read Left -
PIN 11 = Front Right +
PIN 12 = Front Right -
PIN 13 = Rear Right +
PIN 14 = Rear Right -
PIN 19 = +12V permanent
PIN 20 = Ground
Beware: Look at the numbers in the Easylink socket, my plug has wrong numbering !
Easylink accessory connector:
PIN 20 = EXT-CAN High (120 Ohms termination required)
PIN 40 = EXT-CAN Low (120 Ohms termination required)
PIN 19 = M-CAN High (Transreceiver and termination on these pins)
PIN 39 = M-CAN Low (Transreceiver and termination on these pins)
PIN 18 = M-CAN High (Termination here)
PIN 38 = M-CAN Low (Termination here)
PIN 1 = Mic 1 Signal
PIN 2 = Mic 2 Signal
PIN 21 = Mic Common Ground
PIN 4 = Aux Detect (you can disable it within DDT)
PIN 7 = Aux Line In Right
PIN 8 = Aux Line In Left
PIN 27 = Aux Ground
PIN 12 = Ground for reversing camera
PIN 13 = +6V for reversing camera (needs loaded with 300 Ohm to PIN 12, when using 12V camera)
PIN 32 = CVBS differential + for reversing camera
PIN 33 = CVBS differential - for reversing camera
Touch display connector:
PIN 15 = +12V permanent
PIN 17 = Ground
PIN 11 = M-CAN Low
PIN 23 = M-CAN High
