c101 and x20 wire diagram (e30 M50 adapter)

[The Fast One!]

i do believe the adapter to be right as long as your pin chart is for the 88-89 m20.


let me dodble check this real quick,

on the m20 side pin 11 the white/green wire is NOT used


and for the m50 side,

there are 8 wires not used,

colors are,

black/purple
brown/yellow
white/purple
blue/white
brown/black
black/white
black/blue
purple/white

all those are not hooked up and everything else is following addissimos chart,

are any of those black or brown wires supposed to be grounded, I'm going to check and see where they go to see if they should be grounded.

thanks.

it is just an M50 VANOS motor with maroon 413 ecu (checked it and it's fine) also 325i harness, havent confirmed yet if it is from a 93 or 94-95 (I don't know if there different)


I wish I had the money and had been able to get that M52 from you. :(

Mike-

what is your setup looking like? What engine, which harness etc?

[Addissimo]

But the m50 one is non existant.

word.

I have been going off recycled information. Kudos to whoever figured out what goes where for the m50 plug.

I dont really think the diagram is wrong, it all depends on which year car you have and so on. I dont know why people keep these things to themselves, its not like its privledged information. It seems most people to have done an m50 swap know someone who has done it and get lots of help from them. I just don't see how this issue is so clouded. I've searched everything from ETK, ETM, all data, mitchell, online resources, bentley, haynes, and bmw manuals and I get confrimation that this plug exists, but no where does it say what it does (although I know what it does) and what the pins are. Its like bmw made it a big secret for some reason.

I know the above chart for the m20 was printed by bmw and its the same chart I used to get my motronic swap running. But the m50 one is non existant.

[The Fast One!]

thanks man,

I used your chart and it doesn't seem wrong but I can't get the car running and I just want to make sure that the plug is right.

anyone have the m50 one just to make sure

[Addissimo]

I put a disclaimer saying it worked for me... cuz it did. Sorry it doesnt work for others.

Maybe they should post the modifications they have made to it, the year and model of their car, vanos or non-vanos, e34 harness or e36 harness.

Someone should just post them here and turn it into a sticky.

where do you guys get your wire diagrams!!!







I need to check my wiring for my adapter since I heard that addissimos chart is wrong.



I'm looking for the wiring digrams for the c101 connector for e30, I'm 99.99% sure it's for the 88-89 one.


I also need the diagram for the m50 plug. I would need all from 92-95, since I don't know which year motor it came off of.

or just need to know what is wrong on Addissimos chart.




I do not have an e30 bentley, but do have an e36 one. I looked in the bentley for the plug wires but couldn't find it, only the data link connector and ecu and all.


If you have the files and can't post them PLEASE e-mail me at meseetree@myactv.net

Thanks
