splicing wires to make one wire

my ihome is ihm61 which is similar to the im71sc but nit Bluetooth.my question is which wires go with which on the aux it's red,blue,green on micro USB it's white ,green ,red,and black . the original broke it was the combo of them both with USB port but I'm by passing the report only need the aux with the micro so I can listen to music the speaker is awesome but the three way combo breaks and I'm tired of buying them so how do I splice these wires correctly
