In this video I show how to modify the e36 m52 engine wiring harness to fit e30 chassis. This tutorial also works for m50 engines and wiring harnesses from other cars like e34 or e39.
links for how to connect the wires:
www.rmeuropean....
garagistic.com/...
www.akgmotorspo...
What pins/wires mean: www.r3vlimited....
Part numbers:
- The plug housing: 12521707283
- Pin for small wires: 61131376191
- Pin for medium size wires: 61131376193
- Pin for thickest wires: 61131376195
I recommend getting few of the biggest ones and then like ten of the medium ones.

Thanks. Easiest is to just delete the EWS from the ecu: kzfaq.info/get/bejne/r6qIg6WdzZuXdqc.html

hey @pazi88, question. what if i remove those un-sed wires completely from the loom. i mean, re-do the insulation and get rid of everything that is not used. will i face any obstacles with it ? or i wont be able to do that because they are connected anywhere else ? thanks :)

@PocezPanda 4 жыл бұрын

Hey pazi, would you happen to have the wiring harness pinout for E39s? It has 2 or 3 connectors instead of the big X20, and I can't seem to find any info on what wire is what. I could just assume they kept the same colors, but that's a bit dangerous to assume. :D Any sources for that? Or at least the connector names so I can search for their pinouts?

@larheimann4195 10 ай бұрын

Hello, it seems to me, that all the pins you're connecting, into the plug, have the same size. In the discription you mentioned 3 sizes. Could you explain it once again please? Greetings, Lars

@pazi88 10 ай бұрын

Yeah there is pins for three different wire sizes. But with some extra care, you can use same pins for different wire sizes. It of course isn't the "correct" way to do, but fine for me.

Hey Pazi, im trying to learn about wiring and ive been doing a lot of research lately, and i managed to found bunch of useful informations, but i couldn't find an answer for some questions of mine, i'd really appreciate if you could help me. Is there any difference in C101 connector between 4 cylinder and 6 cylinder cars? Is there any difference between US and EU cars when it comes to C101 connector? In other words, can US Bentleys wiring diagrams be used for EU cars? E30 have C101 connector, E36 have X20, and E39/E46 have what? I know there isn't that round plug like in E30 or E36. I'm trying to figure out wiring M52TU/M54 into E30 and i'm not sure what kind of plug is used to connect the engine harness to the chassis. Is there few of them instead of one, and are they called x60004 and x60001? Thanks.

@pazi88 Жыл бұрын

I'm almost 100% sure that those are basically same between regions. The only real difference is that US cars usually have more pins populated. Ie. there can pin for CEL light in US, which isn't there in EU versions. But basics should be same. And yeah e39/46 use two connectors to interface with the car.

Hello, and thanks for doing this wiring tutorial! Very helpful. Quick question... do the connector ends come in packs? Or as individual pieces per part number? BMW want to charge me nearly 8Euro per connector pin (Assuming the part number only gives a single connector)... they cant tell me if the price is for say a pack of ten...? Could you tell me what you got when you ordered that part number? Thanks!

@pazi88 6 жыл бұрын

the part number is for one pin. But normally they only sell those in pack of ten.

Hello pazi88 quick question here is it the same to use a 97 328is harness and modify it like you did or should I look for a 93/94 harness out of a 325. I'm doing a m52 swap out of a 97 328i but the harness looks different from yours thanks in advance. I know I have to delete ews secondary air system to. Also mine has two ecu one for dme and another for trans dme I think.

@pazi88 7 жыл бұрын

Z..... 325 is with m50 so you can't use it with m52. Those are totally different. The harness is probaply different because it's from automatic car. But the modifications will be the same. The second ecu is for the transmission and it's not needed if you do manual swap.

Abs has nothing to do with engine swap, so it's something different. And to get temp gauge working, you need to add the original m50 instrument cluster temp sensor to the m52 and wite it in.
