Bit of a question relating to anyone who has experience swapping motors, I have a 318ci with an N46B20 motor and a full M54B30 donor car for a swap, questions arose around the looms, does the interior loom need to be swapped over too? Asking just before I get stuck in. I'd guess the engine loom obviously needs swapped, but unsure on the interior and other forums and no definitive answer.
