Hi,

Does anyone have or know where I can find the following info?

1. Complete E38 4  letter wire colour codes? eg. BR/WS etc and what colour wires these relate to?

2. A list of the codes for the various connection plugs, specifically, X400, X322, X325, X498 and where these are located in the car?

Thanks.

Interestingly enough, this post was just over on the zroadster forum, by Tim Cullis:

If you are trying to decypher BMW wiring diagrams, it's rather essential to realise that:

BL=blue
BR=brown
GE=yellow
GN=green
GR=grey
OR=orange
RT=red
SW=black
VI=violet
WS=white

Some advice I received a long time ago from wiring guru Ron Styger of Unoffical BMW fame:

In general, a solid red wire is hot at all times.
A red wire with any color stripe is hot at all times after a fuse.
In general, a solid green wire is hot in run and start.
A green wire with any color stripe is hot in run and start after a fuse.
In general, a solid violet wire is hot in accessory, run and start.
A violet wire with any color stripe is hot in accessory, run and start after a fuse.
In general, brown is ground.
Gray with a red stripe is dimmed lighting.

I can't vouch for any of it myself, but Tim generally knows that of which he speaks. Hope it helps!
