If you are going to buy a adapter for Cummins but you are confused between Inline 7 and NEXIQ USB Link 2. This article summarizes some other people’s purchase experience and suggestions, which can be used for your reference. Here we go.
From Mikeservice:
Nothing different other than inline comes with inline harness to plug into any Cummins harness if you can’t talk through oem side.
From Undeadmechanic:
Inline 7 is built by NEXIQ USB Link for Cummins. They slap their sticker on it, and give you the extra harness to plug into the backbone directly.
I ordered an inline 6 to get the extra goodies for benching and they sent a 7 instead. I am not complaining, lol. I have not installed it yet, but it may have a different firmware than the “real” usb link 2. I will find out when I get around to installing it since I now have one of each.
From silnoreki:
Inline have both blutooth and wifi and slighty faster even when looks same. I am happy with my inline7, just 2 cents.
From Sdtruck12:
I can use inline 7 for everything from ddct to jpro and n14, from obd2 tool to new works great for programming real fast. Sometimes cummins only like cummins adapters, like n14 m11 570 stuff like that in my experience at least.
From harobaua:
The two differences I have noticed are:
1.Inline 7 has wifi and bluetooth at the time, nexiq only one at a time.
2.NEXIQ USB Link 2has more protocols than Inline 7, for example the Inline 7 does not work with Hino, Toyota, Isuzu.
After reading this article, maybe you already have your own idea, which one to choose just depends on you.
