Connecting
I got an OBD-2 extension cable with 90 degree ends to make a low profile connection. I cut the cable in half. (Photo!) Now I have a connector with a 12" cable ready to use.
Termination
I don't need termination as long as my cable is less than 0.5m long. (It was 18" but I snipped it down to be on the safe side.)
Pinouts
Signals that matter to me, and the wire colors:
5 signal ground -- orange
6 CANH -- Black
14 CANL -- Green
16 12V always on -- Brown

Interfaces
MCP2515
I intend trying the MCP2515 chip first because it's commonly used. Microchip MCP2515 datasheet
I got this breakout board: Seeed Xiao https://www.seeedstudio.com/Seeed-Studio-CAN-Bus-Breakout-Board-for-XIAO-and-QT-Py-p-5702.html
I got two, so one will have a 6 pin header soldered to the SPI connector and the other will have a Xiao ESP32C6 installed.
Seeed's board uses the TI SN65HVD23x 3.3-V CAN Bus Transceiver so it's all 3v3 and that means it can work with a Pi
