Sales and Wants / WANTED Z3 boot lock
« on: March 14, 2020, 10:17:56 AM »
I'm trying to use the Z3 central locking mechanism with the DNA provided external boot lock. My kit didn't have the complete DNA lock set so I decided to attempt an improvise...

I think I'm making reasonable progress but in the process I've fooked my original lock. There must be plenty of these lying around in people's come-in-handy bins and I'm hoping that someone will have one that they would like top recycle in my direction?

I'm talking about the aluminium bit that the key fits into and to which the central locking mechanism also attached.

If you have one that you don't need, please PM me.

Thanks for your responses.

DNA no longer exists and the people who ran the business can't help.

My kit came with headlight covers but I've over trimmed them. FWIW I'm looking into getting some made so if you too need some then please pm me. The more we order the lower the individual cost as the tooling gets shared amongst all of us.

Does anyone know where I can get a pair of these or who makes them?

Anyone got a spare pair kicking around :-)

Hopefully someone can help me out with this.


I think a couple of us want to get made some of the lower section of the MGB rear light cluster to replace the bulky / boxy version. I'm talking about the red section.

Is there anyone else out there that might be interested in getting some and we'll see if we can get a bulk order placed?

Please PM me if you are interested.

Better still, please PM me if you have any for sale  :D

The problem was two fold.

1. Not knowing which coloured wire did what
2. Not knowing how the "clever" wiper system works

There are 4 wires from the original BMW Z3 / E36  and combinations of how these are paired together by the control system determines what the wiper motor does.

What I needed to know was where to connect each wire on the 5 terminal connector on the wiper motor and the answer is as follows. Please refer to the above photo for the connector pin numbers.

The Z3 wiring diagram shows the colours using German short codes, I've translated these into English full colours and then mapped what the original harness uses to what I had available. I've ordered a 5 pin Lucas plug from Car Builder Solutions and will use that rather than using the spade connectors once it arrives.

The photo below shows how I set about adding the extra earth to terminal 2 of the 5 pin connector which I think is a better solution that the long cable that the DNA video recommends.

So the colour scheme is

Pin 1. Earth BN (Brown) I stayed with Brown
Pin 2. Also earth. This is the cable that DNA suggest making long enough in case you need to remove the wiper motor in the future. I just coupled off pin 1 with another brown cable
Pin 3. This controls the fast wipe setting. SW/WS/GE (Black / White / Yellow) I went with Blue
Pin 4. Switched 12V from ignition. This is the thinner of the four cables BR/GN/GE (Brown / Green / Yellow) I went with Yellow / Green
Pin 5. This controls the normal speed wipe. SW/RT/GE (Black / Red / Yellow) I went with Grey

The second issue was the behaviour of the system, I had read (and ignored) somewhere else on the forum that the wiper system behaviour is speed dependent. At slow / stopped speeds intermittent position seems to stop and the first / normal speed seems to become intermittent. The second (Fast) speed behaves as normal. When I tested the wiper behaviour when the car was static it didn't behave as expected. When I lifted the car and got it in 2nd gear then it behaved as expected.

I hope this helps anyone else that struggles with this.


Build Threads / Wiper motor wiring
« on: February 21, 2020, 05:03:56 PM »

My kit didn't come with any wiring harness / connectors so I'm having to work out how to connect the 4 wires that come from the Z3 bulkhead connector to the wiper motor's 5 way connector.

In the DNA 2Fifty video there is a clip which shows (at 25:43) the wiring for the 5 pin plug (see attached) but I don't see how that relates to the original wiring.

My original wiring consists of:
A. Brown (Looks like earth)
B. Brown / Green / Yellow (Looks like switched live and is thinner than the other wires)
C. Black / Red / Yellow
D. Black / White / Yellow

The Video shows the 5 pin connector as

1. Brown
2. Earth
3. Black & White
4. Green & Yellow
5. Black

Here I'm using the pin numbering protocol from the wiper motor manufacturer's data sheet (see attached)

The manufacturer (Car builder solutions) tells me that the motor wiring is:

1. Earth
2. When the wiper switch is in park mode this should connect to pin 5
3. Fast wipe
4. Switched live
5. Slow wipe

I understand that I have to run a long earth cable to one of the pins, but not sure which of the earths.

Any help would be appreciated.

Did you ever get any? I'm also looking for a pair...

Got that wrong, thankfully

I managed to polish it out, phew!

As the subject says, my driver's side lens had a small accident with an angle grinder. Does anyone know where I can get a replacement?

It's beyond polishing...

For the sake of completeness, this is what my passenger side door handle mechanism ended up looking like.

Thanks to both of you for the feedback. I'll be following up on the leads

Hi Mechman,

Thanks for your comments but they've arrived a bit too late. Fortunately I have a working solution to the door opening issue. I've trawled other people's build diaries and with a bit of help from Grassbank Conversions I've got a good working solution.

The photo shows an earlier version of what I've done. Since then I've replaced the cable with something which is a bit more flexible and I've used aluminium ferrules from my local rope and cable merchants to crimp the cables rather than using the electrical crimp. The original cable was too rigid. Getting the balance between the desired action and applying tension when at rest was a challenge.

The original solution shown here works well except that the door locks won't open if there is any tension whatsoever on the door release mechanism. The problem only shows itself when you lock the doors with the central locking then try to open the doors again.

I bought 5m of 'soft' 1.0mm cable from ebay for a couple of quid (plenty left over if anyone needs some). This allowed me to have a tiny amount of slack before the door release mechanism moves and so avoids the lockout issue.

My kit didn't come with the oval shaped pieces which attach to the door release mechanism so I had to make my own. In the process I modded mine to allow me to loop the cable over an M6 bolt which is prevented from slipping off again with a penny washer and an M6 nyloc nut. This approach allows me to be able to easily remove the door handle if required.

What do your rear lights look like? I've got the MGB lights and am searching for a better solution similar to what the others got with their kits...


Virtually just around the corner, M60 J23

I'll PM you my contact details, maybe we can hook up pver the weekend, I'm thinking Sunday...


I'm close to Manchester and I'm getting to a critical stage of hanging all of the panels in their final resting places.

It's not that I'm afraid of commitments, but... It'd be nice to cast an eye over someone else's work of art before I do anything that would be difficult to reverse?

Anyone close by that I could pop around to chat things over with or that might want to come over here and take a look at my set up alongside yours?

I look forward to hearing from you :-)


2fifty Chat / Re: Harrington side screen trim
« on: November 26, 2019, 07:45:03 PM »
Thanks for your responses,

I spoke to Harrison pointing out the issues with the trim that they supplied. They told me that they have sold these to other DNA builders and they have been fitted without any issues. I haven't broached the issue of returning them yet because I'd like to hear from anyone that has sucessfully mounted a set (or bought a set and given up...).

On the plus side I've contacted my local BMW dealer and they can get me a set of the official BMW bits for around £110, all in which isn't bad.

So, I'm still hunting for anyone that has sucesfully used the Harrington bits???
