Instrument cluster signals I have installed an LQ4 and have a Silverado instrument cluster. The wiring harness was modified standalone. The class2 data does not seem to be getting to the pin at the PCM. The volt, oil press, fuel and temp gages do not work. The cluster tested good. Any ideas?

Need more info......
Year and model (F-body, truck, van, etc.) PCM.
Year of cluster.
Sounds like you might need to perform a segment swap in the PCM logic, but the lack of detail in your post makes it really hard to diagnose.
This question will get more replies in the "PCM Diagnostics and Tuning" section of the forums.
