00 sienna van, radio harness problems

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?

If you have a premium stereo package from the manufacturer there may not be an install harness available. All the ones I found are for Sienna's without the premium radio package.

what is the premimum stereo package?
like she got this van used with the radio in it and the buttons on the steering wheel to adjust the things

now the adapter i bought was from canadian tire and the radio mount for the van so i can just mount it right now cuz i dont see the other radio cvonnections

so what can i do?

Sounds like you have a premium package. Call Canadian tire and see if there is one available. If not you'll have to install it old school. Keep in mind the steering wheel controls will probably no longer work with either installation.

ok ill give them a call, this premium car package is that installed from the factory or is it just chopped off and harness added
or is there a disconnection some where and i can just get a new harness from toyota then?

ok they told me to go to future shop so i forgo to ask when getting this premimum wire harness do i loose the features of the buttons on the steering wheel? or will it still work with the new radio from sony xplode the gf got

The buttons will likely not work with the sony.

ah thats too bad but thank you for the help
