i can't recall if anyone ever tried to put 03+ in their trucks 99-02 along with the a/c controls.

did anyone ever find out if they work?

thanks

The pins are different. 03+ use small pins whereas 99-02 are thicker blades. AFAIK all 99-02 are single climate and all 03+ are dual climate and you need to swap everything. Or something to that effect.

why not just go get all the wiring plugs with enough wires left over to splice into each other? to make them fit.....

The harnesses and boxes and panels are different. For the splicing idea, it could work, but idk about the whole passenger side auto down thing... I would find maps of each before going at it.

Any luck getting those wiring diagrams? I've got a set of '04 switches and am anxious to get them in.
