2007 Toyota audio wiring harness question?

I bought a plug and play audio wiring harness for a Toyota Tacoma 2007 my only question is when you plug it into the truck stock audio wiring female plug the colors don't match color for color this can't be normal, isn't it suppose to match color for color when hooked up. I only talking about the harness adapter to the stock wire female plug to the truck only not back to the radio. Thanks~

 

I purchased a Kenwood HU and wiring harness from cructchfield. The wiring harnness wire colors matched my HU and not my truck, as with all the HU installs I have done. I think the more important thing is to make sure your HU wiring matches your harness. The terminal block on the harness will hook up correctly to any vehichle providing you have the correct harness.

 

To the best of my recollection, that's the way it's been on every off-the-shelf adapter harness I've seen or used ...
