This cable will allow you to use your old USB Link with the new connectors that are now common on 2015 & 2016 model year trucks. This cable will work with the original Nexiq USB Link, Nexiq WVL2, TVIT adapter, and any other datalink adapter that takes the standard 15-pin serial connector. This is a cable.
