Hi Guys, So iv got a fully dressed '87-'88 M20B25 with loom and ecu, gearbox etc all with it lined up. The only problem now is the wiring from the C101 plug which is round and has 20 pins, to my rectangular C101 on the '85 323i. I have started to create a pinout chart which ill upload later tonight, theres just a few wires i am unsure where they should go? There is scarce information about 323i's on the internet, as they were Euro spec and well you know, if its not US spec then no one on any of their forums wants to know about it. I also need a bit of help as to what will go to the C104 plug (i understand this is for the cluster side of things). There is a round connection on the bulkhead by the passenger side, i know this isnt a C101 as i have an earlier car but i was wondering what it actually is. Any wiring help would be much appreciated. Ill upload my chart so far later on. This is the first time iv done anything near this intense mechnically, but thought id try my hand at it. I havent got the engine yet but will have it in a month, so i thought its best to prepare everything now so that its easier when i have everything. The 323i L-Jet wasnt the best starting place but its what i have to work with so ill do my best to make it work. If any of you guys are around Central/West Auckland, and know about the wiring id be real keen to have some help when the engine is dropped in. i HATE electrical systems and having not much experience doesnt really help my cause. Im sure with some help i can get this done successfully, so cheers for any help you can provide me with! Also i know the connector changes around the time this engine was built, so i will check again and confirm. This will probably be the same thread i ask lots of electrical questions over the time of the swap. Thanks!

Hi there, So i have a '85 323i that has a tired M20B23 in it and i was looking to swap in an M20B25. I am confident doing everything EXCEPT the wiring, any tips/pointers/help on this? Also because the 323 is L-jet, what will i need to change besides the engine itself and the ECU to make it a motronic? I will be keeping the auto 4 speed for now as i know its possible but once the engine is done id put in a Getrag 260. I am not doing the swap right now, just need a bit of info on what ill need to do etc. I understand things like engine mounts etc can be used, but i will be upgrading them anyways. Reasons for staying M20 and not going M50/52 is that i have been working on the engine for a while and know my way around it reasonably okay. Parts are plentiful and information is everywhere. Its a cheap simple little engine that i can handle so hence the choice if you were wondering As always, ANY help would be much appreciated as this swap isnt covered a lot on the interweb. Thanks, Rohil
