    Default 1986 Mustang Infor Center won't light up

    The info center on my 86 GT won't light up. The clock also doesn't work. The low fuel light does light up. All of the connectors in the rear seam fine. Any suggestions on what I should check? I would appreciate any advice. Thanks.

    A wiring diagram, and connections and continuity under/behind/to it.

    You didn't mention if anything lights up when you press the Test button, but first thing would be to check
    fuse #6. The module works by comparing the voltage differential across a section of resistance wire in each
    of the lighting circuits it monitors.

    Here's a diagram showing how it's all connected up -
