I am looking for some help identifying wiring for this 86120-90A11 Radio. The PO of my FJ60 cut most of the wiring in the dash so I am trying to match it with the wiring harness attached to the radio. Part of my problem is I have only been able to find a brown, grey, red, light green and blue wire under the dash and the colors are different on the harness and the radio. So I am unsure what is what.
