    Are there a particular ground wire that I shall look out for? Is the ground originally via the screws for the panel?

    I have added a new wire - and hope that this may have en effect on some of the gauges that are somewhat erratic/unprecise.

    I also have two old alarm wires piggybacking blue wires to the speedo? The old alarm device/unit is still connected to the gas pump - but I really want to get rid of it, but don't know how? Since my multimeter skills are terrible.
