Yep - You can plug into the OBDII port.
You turn the key to "ON" (don't start the truck) and hit 'start' on the programmer. As it is initializing, it gives you different information. IF he did not return it to stock, somewhere in there it will say, "Programmer has programmed" - If it does not say that, it will check for DTCs, if there are any it will tell you what they so you can write them down and allow you to clear them (needs to do that before it will program your truck), if there are none, it will then asked if you want to enter programming mode.
You can run the programmer before gauges. I did, but I would try to get them soon. Even after I put the gauges in, running empty I didn't find any circumstances where I could get the EGTs to 1250*. I would make WOT runs and couldn't do it. I can with my 5th wheel tagging along, but not empty.
