ABS Module:
This gives ME nightmares.

There's either some kind of "easy" way around it to be able to make the BCM light up the stop lights (that i don't know of) or the really complicated way of making an Arduino with a Canbus shield fake an ABS module.
I would actually prefer the Arduino-way because that same Arduino could act as a display driver to mimic mechanical gauges.


@Buschi:
Bad VR, bad wiring (corrosion), faulty grounds. I buy most of the wiring parts i need at www.kabelknecht.de.
Drop me a line if you need help. It'll be a while until i am in the North again.

Have you thought about using the ABS module but not installing it to the hydraulic brake system. Just use it to communicate through.
This would allow you to use the brake position sensor and have the ABS module send a signal to the BCM to turn on the brake lights. With that though, you would need all of the inputs the ABS wants to see, wheel speed sensors, steering angle sensor, yaw rate sensor, etc. If you don't use ABS module and you do something different with the brake lights, will the ECM still stay out of 'limp home mode' without those inputs.
Have you looked into reprogramming the ECM? I'm not sure if its possible, but if you could just get the ECM to no look for the ABS inputs, that might be the easiest route.
These are all things I've been trying to figure out while planning my build too.
Good luck, keep us posted.
