The cluster gets all it`s info over the bus (the 2 wires with 2.47V) Honestly it is going to be tough without a scan tool (real one NOT a code reader) to see what is going on as there are far to many variables not knowing what all you took apart, or more to the point, maybe unnecessarily took apart
Make sure you have all the connectors back on the body control module if you removed them before you go too far.
