    Hello All,

    I have two small projects that I would like to make.

    This is for most CJ Jeeps in the '80's. Mine is a 1984, Jeep CJ-7.

    This is a diagnostic unit that connects to a diagnostic plug that predates the OBD-II.

    The simpler version can be found here:

    This page will also discuss and show you the original posters version of the tool.

    Here is the page for the diagnostic connector and such:

    I have the Molex connectors ordered.

    Feel free to reach out if you're you're interested in making this.
