Default Difference between N55 JB4 Stage 2 E-Series and F-Series - 06-02-2015, 08:22 AM

Hi,

i just bought a JB4 Stage 2 (not from BMS) for my E92 335i LCI (2012) with Harness B.

Is there any easy way to find out if that JB4 is really for E9x series and not for F-Series?

The F series harness has longer CANbus wires that come out by the TMAP sensor.

Yep. I converted an E series one over. Also got the EWG board for it and a new case.
Extended the brown and green wires (soldered, no BS crimps), popped out all the DSUBs for the blue and purple patches, along with the red and black wires, reloomed everything to hide the brown and green wires. Easy conversion.
