yes..all the connectors are interchangeable.. like for the back up whites, the breaking tails.. the yellow signals.. i believe the connectors were all specifically fitted to each other.. so it minimizes the mix up. so yes, no mods or wire splicing whatsover needed. good luck.. hopefully you can find a person in your area to swap with.
the wiring harnesses are a bit different from 05 to 06. The 06 setup appears to use a connector, whereas the 05's seem to be hardwired (i could be worng on this...i didnt really investigate it closely). How the wiring is grouped is definitely different, as the bulbs are in different locations. Simple to rearrange.
i'm not a DIY expert.. but really.. it was a easy swap and reconnection. I had mine installed in minutes. The difference was.. the 06 assembly, looked to be "hardwired", but it wasn't. the wires were just better routed and packed along the housing. I remember there being a little metal clip u must undo on the 06, to loosen the wiring.. but it was not big deal. in the end.. the connectors all matched up, and the taillights are working fine. hope this helps.
