Pre-LCI tail lights have:
1- Turn light
2- Reverse light
3- Fog Light that doubles as position light
4- 1 brake light that doubles as position light
5- 1 brake light that doubles ad position light

LCI Tail Lights have
1- Turn signal
2- Reverse
3- Fog light that doubles as position light
4- 1 Brake light
5- 1 Brake light
6- Led rods as dedicated position lights

That is why you need the two extra wires, LCI tail lights have the same functions, but with one more light, if you don't wire them, you will miss one function on each light. It is possible to make them work with LM2 without the extra wires, sacrifying one of the brake lights to make the rods light, but it requires hacking the retrofit kit adapters and probably some coding hacking also.

When you do FA_WRITE on the LM2 it will get your current VIN and vehicle order (VO), the same applies to CAS.

Install LM2, load NCSexpert, open Expertprofile (must be the original untouched expertprofile) and just load VIN/FA/ETC from CAS, edit it to add +MUEB, then FA_WRITE to CAS and LMA, and then SG_CODIEREN to LMA.

Try your LCI tail lights without the new wires installed to see which function is missing.

REMEMBER: To make BACKUPS of everything before doing anything.

If yo go Bruce's cables route i have one set spare of v6 i could sell at discounted price, just plug and play. PM me if you are interested.

I understand you have a 2007 520d, so you have LM2 for sure. LM2 was installed from factory in cars manufactured from 2006-06, but only from 2007-03 they started to come with LCI lights.




Once you have the LCI tail lights working, achieving Ricky's effect is easy, you can achieve it just with coding (harder but cleaner), or just disconnecting the 2 wires that supply current to the two brake bulbs, and connecting them to the fog light. i don't remember the number of the pins and they are different on each light. The rods are always at full brightness when using LM2, so no need to mod anything on them.

I won't recommend having ricky's effect, it is illegal in a lot of countries, and it defeats the purpose of having an OEM LCI tail lights, people would think you have installed a cheap third party tail lights or that you are using a cheap adapter cable which cannot handle all the functions properly.

What i did was code them so when braking only the outher brake light turns on, instead of the two at the same time as it was by default. This way my led rods are still visible while braking, and still preserves OEM look.

But hey, it is your car and it is your choice.
