Wiring harness Q?

[shiftredline]

I was told by Bestbuy that I need a Class 2 Interface cable for my 03 Tahoe stereo. Im putting in an JVC DVD headunit. I was quoted 110 for the harness. I have no onstar and non bose unit. Is this correct and i need this expensive harness or what. If so does anyone know where to get it cheaper. I'm so use to my older cars where it was a $14 cable splice some wires and you where done.

Thanks

You do need a Class II databus interface for all 03+ GM trucks, whether you have on-star, bose, or not. You can find it cheaper elsewhere though.

Thanks for the reply. I was just really shocked when he told me the price. Thanks again

Another Question for ya. I seen one of your earlier post about the GMOS-02 data bus (NON BOSE). I went to a shop and they sold me the GMOS-04 harness. Can I still use that even if I dont not have onstar or bose. Thanks again for your time.
