    Instrument cluster swap

    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.

    Why don't your gauges work properly? There have been countless 96-2000 GMT400 trucks with Gen3 engine/PCM's swapped into them.

    The tach doesnt work right and cannot get the coolant gauge to read properly. I know I can get the pcm values reset, but I do not want to send out the pcm again. Plus I want the factory style trans temp gauge.

    Ok-Got it. The trans temp gauge is a pretty nice added feature.

    Nobody wants to give any hints on how they did the cluster swap?
