Trying to setup a CAN bus sniffer and I haven't found the second HSCAN bus CAN2-2 that OBDLink and ForScan says is there. I have the required HSCAN bus on pins 6 and 14, and the MSCAN bus on pins 3 and 11 (running at 500000), but don't see the other HSCAN bus that OBDLink calls 'Network B' and ForScan labels 'HSCAN3'?
I tried pins 1 and 9 from the following table and had no luck seeing the CAN bus traffic that my OBDlink MX+ is getting updates from. Hoping someone with access to a Mach-E schematic and/or a labelled pinout for the OBDII connector can guide me to the third CAN bus.
Why so I want this CAN bus? The APIM module is located on this bus and has the GPS data that I would like to include in my logging software

CAN Buses on OBD Pins
The OBD-II port has one standard pin pair for a single CAN bus, but many automakers expose other buses on additional, non-standard pin pairs. For this documentation, we’ll use this nomenclature:

The OBD-II port has one standard pin pair for a single CAN bus, but many automakers expose other buses on additional, non-standard pin pairs. For this documentation, we’ll use this nomenclature:
OBD-II Pin Pair | OpenXC Bus Name | Other common name |
6 (+) and 14 (-) | CAN1 | CAN high / CAN low from ISO 15765-4 and SAE-J2284 |
3 (+) and 11 (-) | CAN2-1 | Ford secondary, Chrysler CCD |
1 (+) and 8/9 (-)* | CAN2-2 | Ford: infotainment, GM: J2411 |
* If available, Pin 8 on Ford B, C platforms and Pin 9 on Ford D platforms. This is typically not available. |
