ya you turn the truck on and let it run for a bit and then place the needles on where they are suppose to be. For the Temp, battery, and oil gauges just but them at or just below half. As for the rpm needle I put mine at about 900 RPM, my truck is a 3.0 and your truck might idle at a different RPM. The gas is easy just fill the tank up and place the needle on the full mark. The speedometer needle is the hardest, you have to get a gps that tracks how fast you are going and then you can go 60KM/H and place the needle on at 60.( while driving) It's pretty hard and takes a lot of patience.
If you have any other questions just pm me. I just did this on my ford ranger and I know how frustrating it is but you WILL eventually get it perfectly! good luck!!
