A 'Y' cable for connecting a BlueFIre Black or Green 9-Pin Adapter along with another 9-Pin adapter.
Note that if you have a BlueFire Black Adapter you will need a Black 'Y' cable.
For BlueFire for Trucks customers, this works well if you want to run the App along with an ELD adapter.
You can purchase a green adapter cable from Amazon at this link and a black adapter cable from ebay at this link.
