To mu knowledge its just the engine loom itself mate, unplug it in the engine bay and then drag out the ecu part. Get hold of your 329 loom and replace the engine / ecu loom it is actually really easy.

As for the diff think 320 or good for 325's but 318 I am unsure. Sorry buddy.

Keep the looms on the engines! No need to remove them.
No provision on the 318i body loom for the oil level sensor, so that won't work, but apart from that it's just plug and play.
You need to change/modify the air filter mount for the 320 one. Diffs on 320 and 318 are both small case, and the ratios aren't far different.
