Yes it was my first time... /ubbthreads/images/graemlins/wink.gifBut I bought a reflashed PCM with a 4 position chip from Jody.(I save my original for trips to the stealer) /ubbthreads/images/graemlins/smirk.gif The PCM he sends you will have a cable/wire coming out from the back of it. This cable/wire is attached to your 4 or 6 position selector (whichever you chose). Then you have to mount that selector on your truck (I mounted mine as recommended, under the fuse panel) Then you attach the knob to the selector and tighten the set screw.
You can also just have him reflash your chip, (but down time with your truck because you have to send in the PCM.) There are a bunch of options, all which can be discussed with him.
