AEM X series and BMW G4+ CAN wiring

Hi guys,

Probably been asked before but a search didn't find anything solid.

I have a brand new X series 30-0300 gauge and want to know instead of using the analogue input to the G4, can I use the X series' CAN H and L, and wire it to the CAN pins on the G4?

If so, is it as simple as wiring the matching AEM wires to the same on the CAN/RS connector of the G4 (PIN 2 and 3) 

Attached photos of the AEM and G4.

 

Cheers,

Matt

Pretty much.  You need to configure the CAN settings also.  There is a set up guide for the X series in the help file under G4+ ECU Tuning Functions > CAN > Device Specific CAN Information

Pinout for the CAN socket in the help file is not as clear as it could be as there is no indication of which pin is #1, so below is a pic to help.
