E34 2.0 engine swap to e34 2.5

Well thing is i can't seem to find the X20 plug layout for 2.0 siemens anywhere. If someone has it or can point me to right direction it would be appreciated.

92 year 520 M50B20 siemens X20 plug layout needed ty :)

look at the 93+ ETMs and you'll find it there :)

I think i'm either dumb or blind, i've looked thru 94 and 95 year manuals, both have in component list X20 connector black 25 pin, yet i can't find it in the manual on page 18 ?

Something basic like major plug pinouts don't get refreshed in the ETM unless there have been major changes, like the '87 M20B25 manual is HUGE compared to the '90.

Look at the first M50 manual that used the Siemens.

I've looked thru http://www.wedophones.com/BMWManualsLead.htm can't seem to find it there, anyone wants to give me a direction where to search that manual ?

If you're looking for a pinout that tells you what system each pin goes to too bad it doesn't exsist. You have to go through the etm and find each instance of the x20 and write down which pin goes to which system.

If you are looking for a connector view that tells you the layout and numbering of pins that would be found at the end of the etm in the connector views section.

I'm looking for same thing only for 520 ( this one is 525)

[Adrian_Visser]

Yeah no.

Someone did the research themselves and made that chart. It is not copied from an etm. You should take the 3 hours and do the same, it will give you some knowledge to help you troubleshoot any electrical problems you may have with your swap. That is a great format in the above post I would use the same idea. I just wrote mine out on paper. I will I suppose have to put it on a spreadsheet sometime.

Oh ok tnx for the reply, i'll do that!
