Well here goes.... I have a 2005 1500 extended cab 4x4 5.3 V8 that my dad gave to me after my mother passed away. The truck runs like a top with no issues besides RUST and a lot of it. I purchased a rust free southern 2003 1500 extended cab 2x4 V6 and plan to swap cabs. I originally planned to switch the whole interior over from the 2005 to the 2003 cab. Now, to save some time and hopefully lessen the headache could I leave the interior as is? Will my wiring from my 2005 hook up to the wiring on the 2003 dash? The only difference I see between the two is the 2003 has the option to turn off passenger side airbag.
