Here, we’re talking about NEXIQ USB Link 2 China clone for good price and quality.
How to choose a good cloned Nexiq usb link 1 or 2 and cables:
All Nexiq have the same functions, but they are produced in different factories. (quality differs)
What’s the difference between Nexiq 1 and 2?
Nexiq 1 is the past, Nexiq 2 is the future.
NEXIQ USB Link 1 is discontinued. no more updates but for most people it will still work just fine.
Nexiq 2 is the current model and has more future potential than what the Nexiq 1 could do.
Cables for each are different so they are not interchangeable. When ordering, you should make sure you get 3 different cables. The standard 6/9 pin y-cable with the green connector on the 9 pin plug so you can communicate to the newer 500k baud network. A standard OBD II cable and an OBD II Cat cable to talk to Caterpillar engines in GM trucks. If you need to communicate to trailer ABS, you will also need a PLC adapter.
Do you recommend wifi or bluetooth?
Both will work off bluetooth but I find bluetooth very slow. It’s faster and easier just to use a cable to connect to the laptop. The cable is a standard USB “printer” cable. I like using a 5 meter cable so I can move the laptop out of the truck is I have to. There are times I’ve used the laptop on the other side of the truck and even under the truck. The long cable makes it easier. Occasionally, I’ll use bluetooth Heavy Duty Truck diagnostic Scanner.
