Re: Digital dash help

Go to google
Type 88 firebird PDF
Click on the link
In the upper right corner you can either browse or try to download it.

Section you are looking for is the electronic dash.
It has some wiring diagrams but not all.
For some more wire diagrams, try to locate the body manual for the 88.

Chiltons and Haynes guides have some more info.
