No, the wiring instructions I have for the swap are from the US. It turns out the UK harness is different to the US one. We don't have the smaller engine connector as our DME, battery and fusebox are all on the same side. After about 3 hours of looking at wiring diagrams for the check engine circuit, UK 318ti's are wired the same as UK 325's so i dont need to swap any wires as instructed by the US swap instructions. Good bit of info for any UK M50 swappers. The only changes to be made to the wiring for a UK M50 swap are to cut the EWS line to the DME (provided you are using a pre EWS engine and DME, ROad speed signal from Cluster or radio to Engine connector and fuel consumption wire from Engine connector to cluster. And the power cables from battery to starter and fusebox etc. Pretty easy really, now ive done the research. (which nearly fried my brain) These old BMW wiring books are so confusing!
