Since we have had various experiences of needing reprogramming or not, even on two '03 models, I wonder whether the software version the vehicle is on has any impact on the need to reprogram for the wiring harness. My vehicle was never flashed or changed to a newer version, while I am sure that Weasel's has been updated. Just an idea.
