I have no idea yet, but to be honest if the loom does need swapping I'd just put a digi in it, as I've done the carb to digi conversion before, and after owning both Kjet and digi I'd rather have digi anyday. Do the mk1 cabbys still use the same CE1 fusebox as the pre 90 spec mk2 digi? If so should be an easy plug and play swap, as long as the loom passes through the same place as a mk2?
