Regarding recoding my new ABS module, I contacted my tech last night who told me that the car runs a self diagnostic every 200 miles or so and if I were to leave the module as is then the car would detect something is wrong and all 3 lights would come back on!!!!!
So for the sake of £50 or so ive arranged for him to code it today.
Better safe than sorry I say.
I will try post a pic of the old module although you mentioned the heavy guage wire in the middle, mine didnt have that and all wires were silver mine is the DSC111 Bosch 5.7, either way I think you would have to be a magician to fix it.
