I ordered this and misunderstood what it truly was. It appears that it will work as it should. It seems easy to use at it is plug and play as long as you know where that port is in your car.
Hi, thanks for the honest feedback! We really appreciate you sharing your initial confusion — it actually helps other buyers understand exactly what to expect. You're right that it's plug-and-play once you locate the OBD port (usually under the driver's side dashboard). Glad to hear it's working as it should now! If you have any questions as you continue using it, feel free to reach out. Safe driving!
I like it gives a new look to cracked dashboard
I installed this on my 2021 GMC Sierra 1500 Denali truck with a 6.2 engine. This is literally plug and play. It works perfectly as described and allows your engine to run correctly without dropping cylinders or shutting off at stoplights. It allows you to use your engine as it was built, and gets you up to speed quickly by disabling the function that tries to save gas by shutting off cylinders. The size of it is perfect and tight fitting in the OBD2 port, it��s durable as well as out of the way when driving. I personally leave it plugged in and have not seen any drain on battery life.
Good product at a good price
