Okay, ive searched a lot and cannot find a actual write up of how to put a NBS cluster into a OBS truck. What is involved? Cutting and splicing of wires? I almost got a cluster from a 99 Silverado last weekend from the boneyard and was able to find the same year truck as mine, but it wouldnt fit, and there is a pigtail that attaches to the top. I really like the look of the newer style gauges plus id like to have everything function correctly.

BTW, my truck is a 98 Sierra with a 5.3/4l60e.
