x20 Connector Conversion Help!

[MtechTone]

Sorry guys this isn't E30 related but in my visits here I've noticed how busy the engine swap forum is and the M5x engine is a popular upgrade, so I'd very much appreciate your help please!

I'm currently converting my 1999 316i compact with a 2.8 from a 1996 328i saloon. But there are some differences in the x20 connectors....

I have marked those that appear to be a match with a *.

316i compact x20 (car side)-----------------------------328i x20 (engine side)

Pin no. Colour Function -------------------------------- Colour Function
1 YEL - ABS/ASC control unit -------------------------- not used
2 BRN - ABS/ASC control unit -------------------------- not used
3 BLK/GRN - Exhaust gas valve/temp ? ------------- GRY/VIO ?
*4 BLK/BLU - AC compressor relay ------------------- BLK/BLU Air con
5 not used ------------------------------------------------ BLK/GRY Aux. fan/diagnostic ?
6 not used ------------------------------------------------ VIO/GRY ?
*7 GRN - Immobiliser device --------------------------- GRN ?
8 BLK/WHT - Fuse/DME relay -------------------------- RED/WHT ABS ?
9 WHT/GRN - ABS/ASC control unit ------------------- BRN/RED ?
10 BLU/YEL - Reverse light switch ? ------------------ BLU/YEL Static oil level ? (colour matches...)
11not used ----------------------------------------------- BRN/YEL Water temp
12 not used ---------------------------------------------- BRN/VIO Water temp
*13 GRN/VIO - Fuel pump relay ---------------------- GRN/VIO Fuel pump
14 WHT/VIO/YEL - Fuse/OBD con. ? ------------------ not used
*15 BLK/GRN - Unloader relay ? ---------------------- BLK/GRN Unloader relay
*16 WHT/YEL - Diagnostic/DME ----------------------- WHT/YEL Rx data/diagnostic
*17 WHT/VIO - Diagnostic connector ---------------- WHT/VIO Tx data/diagnostic
*18 BLK/YEL - Starter ----------------------------------- BLK/YEL Starter
*19 WHT/GRN - Diagnostic/instrument cluster ------ WHT/GRN Service reser/diagnostic
*20 BLK - Various control units ------------------------ BLK Various control units
*21 GRN - DME/ignition switch ------------------------- GRN Igition
*22 GRN/WHT - Fuse/various control units --------- GRN/WHT Fuse F26/ various sensors etc.
*23 BRN/GRN - ? ----------------------------------------- BRN/GRN Oil pressure
24 GRN/YEL - OBC --------------------------------------- WHT/BLK Fuel rate/MPG (a match?)
*25 BLU Instrument cluster ---------------------------- BLU ignition warning

The colours were read from the connectors themselves, it's just some of the functions I'm not sure of.

Could people PLEASE fill in the blanks or correct any mistakes.

Also are they all necessary - sounds daft, but for example would the '96 328i saloon of had ASC like my current car...?

Many thanks

Mr brian Moore where are you if ou have no luck here fella ring Ant at A-Tech(01959534718)
i know he has a diagram somewhere

[DanThe]

Where have you got those pin No's and colours from? Have you physically opened the plugs and looked as they dont look right to me?

3 is ABS supply
8 is for the fault light
24 is fuel rate

Cant think of any others

@fowler - I was in touch with Ant before taking on the conversion, he said to email him but he hasn't replied I think I may need his help unless I manage to go it alone...

@DanThe - The pin no's and colours are all correct and yes, I opened the plugs.

I've just been and double-checked them. I think pin 8 on the car is actually BLK/GRY, not BLK/WHT. Other than that they're right.

[fowler]

his email has been up the swanny fella for a while mate
drop me a pM with your emai address and i can try and sort something out with him as i am down there next week

[DanThe]

Take no notice of those I posted, just looked at my wiring diagram for my M52 and its different, must have M50's on the brain at the mo

[fowler]

lol M50 is ok M52 is so strange it differs from each vehicle it has been taken from.

[DanThe]

Tell me about it, nothing simple about M52's!!
