How to fix neutral light , tachometer gauge not working.

I think many of us have been in a similar circumstance, limited knowledge, limited time to work on something, limited space or place to do any work, and possibly #1, limited funds. As the saying goes, "no pot to piss-in, nor a window through-which to throw it."

Hopefully the O.P will be able to use the factory service manual link posted, and the knowledge shared by MaxMidnight to solve the issues.
