Hey guys, I finished my conversion from auto to manual like 3 days ago.
I still drive without reverse light..
I want to do it the right way, means that the signal goes through the LCM and DDE
because the PDC should turn on when i switch to reverse..
sure i can wire ignition 12v to the reverse and to the lights.. but then i should press the PDC button everytime.. i'm not sure if the PDC will work either .

Can someone help?

I already know, that the autobox sends a Bus (?) signal to the dash cluster, and from there goes the signal to the DDE? :dunno:

could i connect 12v to a pin from the autowire ?

I think you may find the wiring diagrams on BMW Planet helpful:

But essentially, to have working reverse lights, you need to run a wire from the transmission's reverse switch to, I believe, the DME.

And the same switch source needs to run to the IKE as well for the R to light up, the lights to come on and the PDC to work

The gear position indicator is turned off in the IKE, no? Or does the R still illuminate anyways in manual e39s?

Okay, so the 2 Pin connector from the manual box should go to the IKE (the dash cluster) and from there the signals go to the DDE to turn on the PDC and reverse lights?
in which pin should the 2 cables from the manual box go into the dash cluster? :dunno:
i dont understand much in WDS

This may be helpful. I stole this from e46fanatics.com user Ivegotissues666

Now that the drive train assembly is complete, we can work on some smaller things like wiring up the reverse lights and clutch switch. For the reverse lights all I did was remove the plug from the transmission once it was installed. I soldered 2 wires to the 2-pin plug and used heat shrink tubing over them.

I reinstalled the sensor back on the transmission and ran the wires to the glove box were there was a reverse light terminal above the fuse panel. I simply used the OEM connectors I had from my previous retrofits to install them just like OEM. Just a note the blue/yellow wire is the trigger wire for the reverse lights.

Ran the wires like the autos harness was.

To the fuse panel&#8230;

Ok that was simple enough now for the clutch switch and clutch switch module.

The module is attached to the clutch master cylinder and the clutch switch is mounted on the pedal assembly's frame if you want to call it that. Anyways basically you just connect the wires of the same color to each other since the module has to connect to the clutch switch. The only drawback is that BMW only gives you male connectors for some odd reason and there were no female connectors, so I had to improvise with whatever left over BMW connectors I had. And it turned out I had just enough of the appropriate pins and connectors.

Both clutch switch module and clutch switch:

Pin 1 - Goes to Ground
Pin 2 - Goes to the DME connection at A60004 pin 23
Pin 3 - Goes to Fuse position #9 (5 amp fuse) Brake pedal

So all I did was wired up the switch and module and tapped for ground and the brake pedal wire at the brake pedal switch located right behind the brake pedal. The pin that goes to the DME I ran through the firewall and into the DME connector to the appropriate pin out.

So in other words, to get the reverse lights to function, you can wire directly into the panel above the glovebox fuses. I don't know if that activates the PDC or not. You'll need to study the WDS diagrams for your engine and model year to see if an additional connection is necessary.

I still haven't purchased the service manual... Probably should get on that!

Pin 25 in connector X101114 on the cluster appears. To be the one I needed to have connected before my reverse lights and PDC worked.. Oh and the R doesn't work in mine either, it doesn't light up on the manual cluster at all.

so does the Pin 25 in connector X101114 need 12v?
or does the blue/yellow wire from the behind of the glove box ned 12v?
or dies the blue/yellow turn on the reverse lights when it connects to ground?
i need info like this.. so i have 2 wires from the manual box which close the electrical circle when reverse is in gear..
and i am really too dumb to understand WDS :dunno:
