Will this work on N20 EWG?
1 Attachment(s)
Picked this up from a F10 520i owner. I have a few questions which I hope someone could help with:

1. Will this work on my F30 328i N20 with EWG?
2. Can this use the latest firmware? If yes, which one should I flash to? N20_OBDII_PWG_6.hex or N20_OBDII_EWG_6.hex?
3. Can this work with the latest revision of the JB4 connect kit?
4. The harness comes with 4 pairs of connector: rainbow, brown, black and blue. I know for EWG I can skip the blue connectors. How about the black wire connectors?
5. The harness also comes with a ground cable (and I think also a red power cable). Do I need to hook them up? If yes, I assume black to shock tower nut and red to +ve terminal?
6. Anything else I need to make it work?

Attached is a picture my JB4 for reference.

Sorry for all these questions. Really want this to work for my car.

No, this is PWG.

DON'T load the EWG firmware as the JB4 is PWG.
You can install as-is and use map 1 and 2 with the PWG firmware on it.
You will just skip the boost solenoid connector and install the rest
