I don't have an OBD port. What should I do?
The easiest way to install an OBD device without the OBD port in your vehicle is to find an adapter according to the Diagnostics port type your vehicle(s) have. There are many different adapters depending on the port type, as well as the vehicle. That's why it's important to be sure which port you have to find the best solution for you.
Identify diagnostics port type
First, you'll have to identify which diagnostics port you have in your vehicle(s) to ensure you have the correct adaptor.
Here are a few ways to find out what we wanted to show you. First, there are three main types of diagnostic ports, 6-pin (J1708), 9-pin (J1939), and OBDII’s. Generally, light and medium-duty trucks use OBDII ports whereas heavy-duty trucks use 6-pin or 9-pin ports. Volvo and Mack trucks with OBDII ports use a different, more heavy-duty cable.
6-pin (J1708)
9-pin (J1939)
OBDII
Diagnostic ports are generally located below the steering wheel on the left side. See common locations marked on the graphic.
Your vehicle’s engine type can also be used to find your diagnostic port. Below is a guide on how that works.
