J1939-Y0 Universal Cable

This 9-pin J1939 cable with a configurable mounting bracket is suitable for most modern heavy-duty vehicle operations. 

BJ1939-Y0 and VG	Clips & Accessories

Screw Clips (Red)	Key Points
	This mount type is common in Navistar-International Trucks.  The red clip holes match with the mount clips inside the truck.  Use existing screws to fasten the new connector to the mount.

Flange Clip (Blue)	Key Points
	This mount type is common in Freightliner Trucks.  The plastic retainer clip can be hard to pry open. We advise using a flathead screwdriver to pry open the plastic retaining piece to remove the connector.
Flange Mount in Newer Vehicles	Flange Mount in Older Vehicles

Jam Mount Clip (Yellow)	Key Points
	This mount type is common in older or larger trucks.  We advise using a combination of provided washers and nuts to fit your application.  Make sure to tighten the nut firmly on both sides so that the connector does not spin.

ACC-BPC Cable

Tools Needed: Voltage tester or a multimeter.

To install a gateway with an ACC-BPC cable, you will need to locate a wire in the vehicle that is Positive and only On when the vehicle powers on.

Examples: Ignition Line, Fuse Box Slot, or any 12V positive wire. 

In order to find a positive wire or fuse box slot, you will need to use a multimeter or a voltage tester.

1. With this tool in hand, turn the key of the vehicle to the On position and test the wire or fuse box slot that you’d like to use to make sure that it is Positive.
2. Once you’ve confirmed this, turn the key to the Off position and confirm that the wire/fuse box slot is also Off and not drawing any power. This will ensure that the device goes to sleep while the vehicle is off and will not drain the battery.
3. Once you’ve found a power source that is Positive, simply wire the Red Cable on the ACC-BPC to that power source. One item that you may find useful when doing a fuse box install is a fuse tap.
4. The black cable on the ACC-BPC is the Negative (ground) cable and should be connected somewhere on the body of the vehicle as the ground.

Heavy-Duty J1708 with USB Cable

Please note that if you are also using a Camera or an ID Reader, you will need to install a USB Hub. Please reach out to support if you did not receive one.

RP1226 Cable

Beginning in the model year 2019, heavy-duty vehicles manufactured in North America by Kenworth, Peterbilt, Freightliner, Volvo, and Mack began including an optional dedicated diagnostics port for telematics devices, known as the RP1226 port.

CBL-VG-B1226 is the Samsara VG cable compatible with this type of port. If available, it is the preferred installation location for the Samsara Vehicle Gateway.
