Freelander ecu problem

My 57 plate HSE Freelander wouldn't start and the RAC started it and told me to take it to the nearest garage because the ecu wasn't communicating, They sent the unit off but it was unrepairable
Was told new parts would cost more than the car is worth and they would get parts from a breaker which they did but not everything is working now especially the ABS i have found a HSE the same year and model as mine being available for parts so does anyone know what parts beside the ecu i need to get to be all compatible . The garage says needed is fuse box ,key module ABS module ,instrument panel
Any help please
