Hello Austin, if you look under your dash near the steering column and see the OBD-2 connector, this will be able to plug in and function. One caveat, though, is that your ECU must report the sensor readings to that port. Many sensors report anyway. If you have the OBD-2 port 99% chance you will have no problems.
I don't believe there is any updates. All it's doing is drawing info from the computer. So if the computer does not put out the information then you won't receive it. I've been using it for 3 years now. I love it and no issues at all. I've used on 6 different vehicle ranging from 2003-2008. Honda, gm, and ford. The only draw I know Is that for check engine lights it only gives the code number. No issue really just look it up haha. I mainly use the gauge for intake temp, water temp, throttle position, and battery voltage. Hope this helps..... Side note vehicle must be obd-II... Like 96 and up vehicles
I hope that I can help some, you should still check online or even call the ScanGauge company, they are incredibly helpful. I have used this on Fords from 1995 to 2006. Chrysler Jeep 2011, so it works if you have OBDII which is the same port on your Dodge, so it should work. I would say from my experience that it will work. I love my ScanGauge, just make sure that you unplug it and hide it when you go in for Smog check or they ding you for having something plugged into the "government port," that is what the smog checker said to me.
