aldl.conf
This is the main configuration file and I treat it as a global config file. This is the file that aldl will look at. There are some key includes to keep in mind:

* DEFINITION - this is the specific definitions file for my truck. I just named the file v2500.conf. You can name it whatever youwant - just reference properly here. The file path must be absolute. The line in the file: DEFINITION=/etc/aldl/v2500.conf

* PORT - the USB address for your USB-Serial adapter, which is used to connect to your OBD-1 connector under your dash.
You can find it by doing a "lsusb". Your output will be something like this:

root@raspberrypi:/etc/aldl# lsusb 
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. 
Bus 001 Device 004: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

The line in the file: PORT=i:0x0403:0x6001

I just left the other settings alone in the file. You may find a need to tweak them.
