so it still not working after the cluster has been rebuilt, I noticed that the N light does not turn on, same for the shifter area. Anyone have any ideas what that is?

so I have confirmed that cruise control also doesn't work.
I have looked at the diagram and also the alldatadiagram. Signal from the source system goes to the tacho and speedo. There is a 10A fuse there which is fine (tested).
Basically
From
Power Source System > 10A GAUGE > Tacho
Power Source System > 10A GAUGE > VSS > Speedo / Trip Meter
A/T Indicator SW > Neutral
haven't looked at cruise yet, all of those are connected to the harness that goes to the ignitor and transmission vss.
Also, can a loose battery connection cause all this?

just to answer the thread, finally found the answer...the harness behind the engine was stretched some how and we just replaced it with a new harness.
