I completed my convertion yesterday, however i cannot get the car to run. I have changed the ews box, key, transpoder etc. Before the car would turn over with the old key, ews box etc. So i changed them to the 328 ones, which will then marry up with the ecu. However the EWS Box on my 318is is black and the one that i have installed from the 328i is white? The boxs also have diffrent HW and SW numbers. Counting the pins the 328i also looks like its got another wire on it. Does anyone know anything about this and the best ways in which to solve it.
