cess relatively easy.
There are some changes in the component descriptions
between the EZ Zone system and the Auto-Zone sys-
tem. It is important to understand these differences
before you begin the upgrade process.
Many of these components look similar, however, in
some cases they do not function in an identical fashion.
Having the wrong component installed can cause im-
