Disconnect the temp sensor on the radiator and see what the gauge says. If it is still pegged hot then there is a short somewhere I'd guess.
You should also check the pinouts for all of the engine bay connectors and see which might be different.
The manual and automatic harnesses might be different, I never checked but there are extra signals for an auto so it is likely different and BMW does not just use a "one for all" like domestics, there is a specific harness for each set of options (like there is no fog light wiring in cars that were built without fog lights).
Good Luck.
