 Over the years, HD has grounded the Sportster electrical systems in a number of ways.
-In the early models (typically, 1993-earlier), **components were grounded to the frame** at a nearby point while power was distributed throughout the system on a minimal number of wires in the wiring harness. There could be as many as a dozen points on the frame used for grounding. The front lights & instruments were grounded thru a connecting strap between the fork risers & the handlebars.

 ====== 5 Volt Sensor Supply ======
-Starting with the 1998 Sport model, the ICM/ECM has provided a +5v power output for various sensors. The MAP sensor seems to have been the first sensor that requires such a voltage.

-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.

-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.
