-Below is a listing of where the +5v supply is connected for various years and various devices along with the listing of where the similar Sensor Ground wire connected. Notice that not all devices that were powered by the +5v supply used the specialized sensor ground connections.+Below is a listing of where the +5v supply is connected for various years and various devicesalong with the listing of where the similar Sensor Ground wire is connected.

-These connections do not have a history of failures, but if you problem symptoms on multiple sensors, be sure to trace out these lines (both supply & grounds) to eliminate them as a potential source of the issue.+These connections do not have a history of failures, but if you have problem symptoms on multiple sensors, be sure to trace out these lines (both supply & grounds) to eliminate them as a potential source of the issue.
