Tail light wiring?

Can anyone identify the wires running into the plug in the tail lights?

There are five (brown -- presumably the ground -- +4 others ) on each side.

Specifically, I'm trying to identify for each side the wire color for the tail light, turn signal and stop.

Thanks.

Neil

Neil,
Here is what I measured on my rear driver side chassis harness tonight:

(3 pin conn)
1- running light _ grey w/ purple
2- ?? _ black w/ yellow
3- neg (-) _ brown

(6 pin conn)
1- turn sig _ blue w/ green
2- backup _ black w/ purple
3- brake _ grey w/ yellow
4- ?? _ green w/ yellow
5- neg (-) _ brown
6- ----

The passenger side should follow same pattern; let me know if you need more and I will check.

From the attached OEM tow hitch module installation instructions (sorry dutch version):

- image 082 0052 Z, page10, you can see the brake light is spliced around the passenger trunk hinge from a Black-Yellow (trunk 3rd break light) wire.

- image 082 0053 Z, page 10, Blue-Brown at the passenger side rear light connector is the running (LED) rear lights connection. This Blue-Brown wire (As well as the 2 Can bus connection wires) already spliced at the taped up wire loom behind the module tray location depicted on the top image on page 10. These splices are clearly intended for tow hitch (and PDC) retrofits for the general E82 platform.

The TIS schedule for the rearlight connector will be searched and posted later.

No worries, I only discovered the splices when I had already connected to the connector. This is the rear light related WDS stuff that I dug up. If you need anything else/more you gotta help me help you with some specific questions.

With the same end goal, started with the electronics and installed the OEM trailer module. Still deliberating which mechanical version of the hitch I'm going with. If you have any side shots of your mount without the fender, those would be helpful.

forgot to mention:
- the files are based WDS version 12 for cars as of 2007_9
- the connector at the passenger side tail lights is numbered X339

Good stuff, but -- unfortunately -- the wires on my car don't correspond to the colors indicated in the diagrams.

Not a big deal, since pretty easy to check which wire is getting current for brakes, for directional signals and for running lights. I'll just need to check each wire on the right and left tail lights.

I'll be using a Tow Ready ModuLite HD Protector, a circuit protected trailer light power module.

I posted a couple of pix of my hitch here: http://www.1addicts.com/forums/showthread.php?t=900446

Let me know what you're looking for and I can post some more.

Thanks.

Neil

EDIT: FWIW, the five wires on the left side tail light connector (front top to bottom) are brown, green w/yellow, grey w/yellow, black w/purple and blue w/green. On the right side, they are brown, green w/red, gray w/blue, black w/purple and blue w/brown.

EDIT #2: The above is for the larger connector. The three wire connector is as follows: left side -- brown, black w/yellow and grey w/purple; right side - brown, black w/blue and grey w/yellow. Done now!

Sorry about that, nevertheless I'm sure you'll do just fine. There's lots of good analog stuff on this car for us to play around with ;-)

Bummer about the WDS V12 info not being up to date anymore. I'm trying to get the right stuff (ie LCI updated), but BMW has gotten much tighter on controlling access to TIS, WDS and EBA documents. If I do get the right stuff, which i'll check on my own car first for accuracy, I'll post it here for completeness sake.

Wired 'er up and all is working properly

For anyone tackling this in future:

Driver's (left) side:
grey w/yellow = brake light
blue w/green = turn signal
grey w/purple = running lights

On passenger (right) side, all you need is the blue w/brown for the turn signal.

My 1M w/trailer is now ready to make its debut next weekend for an event at Summit Point.

Neil, I like your trailer. Looks narrower than most I've seen at the track; most of them load the tires tranversly.

You almost don't even notice the trailer if your following it, I think the great looks of the car may have been a factor though.
