@maaii hi, i was looking for you on another forum and your frend sb2002 advised me to find you here.

I have oem taillights and harness from eBay. But I am not enough experienced to do it by myself. Are you able to provide me some instructions that will help me? My email is stajniakotowo@icloud.com

DIY Car Upgrade Mini Clubman S F54 To LCI Union Jack Tail Lights

Edit 23 April 2026 : Hi, after some visual researches I realized that the black connector (the small one) of my Aliexpress harness version was mounted up side down !
I have to unpinned it, turn it to 180 deg and then repinn. I hope it will help someone who is stuck like I was.

Hi I have a 2019 Pre-LCI Mini Clubman S All4 and interested in retrofitting with new LCI UJ Tail Lights.

This is a long thread, over many years, and it seems like the most people have gone with @maaii solution, buying his adapter cables then doing some programming using BimmerCode. I have reached out to maaii with some questions which he has very quickly replied to all. I am comfortable with BimmerCode.

Just still a little confused on which tail lights to buy to use with maaii's adapter cables. ??

I see that esctuning.com has these LCI UJ LCI tali lights for sale, you need both a left and right unit each costing $436.99
https://www.ecstuning.com/b-genuine-...t/63217487795/

But I also see offered on esctuning.com this tail light set (both right and left units) costing $478.79 and being sold for an upgraded for Pree-LCI cars. No mention of adapter cables or coding necessary.
https://www.ecstuning.com/b-ziza-par...1-f5417-rd-a~/

Seems like there must be some difference in functionality between the two UJ tail light product offerings, but I don't understand what that is and which ones should I get to use with maaii's adapter cable. Big price difference between the two tail light products.

Thanks in advance for any thoughts.

The adapter cables that Maaii sells are to retrofit Genuine Mini taillights whereas the cheaper ECS lights are a knockoff version. I personally went with the Genuine Mini lights bc in the past, I have found that there could be visibility issues with cheap LED's not getting bright enough in the daytime. As for some cost savings on Genuine Mini parts, I would recommend searching on eBay for used left and right taillights. Just make sure that when buying the lights separately, the specs match (make sure they both say SAE or ECE). Otherwise you will have different coloured turn signals (SAE = Red turn signals, ECE = Amber turn signals)

 

@Aderan - Thanks for the information clarifying maaii’s cable and I’ll look for a set of Genuine Mini Tail Lights.

Hi, I'm stuck at this step, did you fixed that ?
I'm very interested by the solution.
Thanks

 

Hello everyone,

I was able to get a set of 2022 OEM UJ Tail lights for cheap. I see the adapters with the blue connectors are widely available on eBay. But there don't seem to be any clear instructions on how to do the cable swaps in the footwell. I understand I'll need a tool to remove the cables, but do I need any extra cable for the wiring? Are they available to purchase? Does anyone have any more detailed instructions?

Thanks! Pat

 

Hello,
Maybe this video could help you…

 

Hello, Is that clearest for you ?
​​​​​

 

I was able to figure it out. I had to ChatGPT how to slide the connector out of the cover. But other than that it’s wasn’t bad.

 

When you brake, do the brake lights or the fog lights appears ?

 

Yes. I actually did have an issue with the brake lights, but it was because I had swapped the wrong pin 32 cable. But I did notice that the brake lights are now only on the UJ lights and not the bumper lights. I’m in the US and apparently we don’t have rear fog lights. Are the bumper lights useless now?

 

If you have the correct coding, the light on the bumper will illuminate when you open the tailgate.

 

Just tried it and they don’t light up. Do you have the coding required to do this? I’m using Bimmercode.

 

Great ! Good job ! For my part I'm still stuck with my fog lights instead of the brake lights…
FRPhilippe, nosidept, pasaporte,anyone could help me please ? Should I contact Bimmercode ?
