hi i bout a radio harness for the 2000 sienna van for her new radio i did the crimping of them and when she brough her car over i was ready to install it, but the wiring harness in there will not adapt to the one i bought, its got 2 sets of plugs that dont match any of the adapter connection i have plus it has like 2 radio antenna plugs i guessing one is the sterring wheel adjustments for the radio.
so i like to know what wiring harness do i need? or is there a hidden one in there or something?
