Jb4 Stage 2 4 extra Wires HELP!!

Hello, i just bought Stage 2 JB4. I followed instructions online for installation. But i am stuck at the last part. What do i do with the four extra wires? Ground, red, brown, green. Where do they plug into? Pictures Please


I tried to follow the instructions but it fails to show pictures for the F10 so i am unable to tell where each one goes

Just installed the Jb4 Stage two. Unfortunetly i did not have the right connections for the 4 wires im guessing. Although according to that link you can just set the 4 wires aside. Which i did. Now reconnecting the battery and starting the car i receive a DRIVETRAIN MALFUNCTION CODE...

Any help?

The control box is supposedly different between S1 and S2 so you can't just run it without those wires installed according to Terry. If your car doesn't look like the pics posted then you need to run only S1.

yes i had the same thing happen to me. I don't have the CANBUS hook-up like the pictures shows. I also got the drivetrain malfunction and engine light. I contacted Terry and he told me i can only run stage 1. They sent me stage 1 but haven't installed it yet. My car is in the shop for scheduled brake service.

My 2011 535i doesn't have the CANBUS location like it shown in the instruction. Does anyone know where to find the CANBUS wire harness?

If you have a 2011 I think you are stuck with Stage 1 only.

My 2011 does have the CANBUS wiring so there has to be something else besides the MY that dictates its inclusion on the vehicle.

Nope, i got my Stage 2 installed a few days ago. Finally got it too work. Improvements are very noticeable, even in casual driving without the Sport Mode

The malfunction i figured out was a miscommunication between some wires. I was also able to figure out i DO have the right corrections, i was told i DID NOT. But fortunetly i did and was able to get in installed correctly.

First day i did not notice much
2-4 days later improvements are very noticeable

I finally installed mine on Friday. Drive it locally and noticed a light difference. I did a trip today which was about 300km and really noted a big difference. So far I am very pleased !

How did you get it to work? My harness does not have the same color codes as in the N54 tech install manual. What did you hook up brown and green to?

I have a 2013 F10 535Xi

Thanks.
