Wire schedule

Wire	From / To	Gauge

This configuration removes wire connection(s) whose terminals are no longer available.

You can undo this change.

Clear the current canvas. You can undo this change.

Drag components into position. Snap guides help line up rows and columns. Choose two terminals to connect them.

Select a component to change its options below. Select a wire to set its color or gauge, or insert a fuse. Double-click a wire to pin its route; drag pins to adjust them.

Space + drag pans. Arrow keys nudge a component; Shift makes a smaller adjustment. Delete removes a selection. Undo restores it.

Limitations and checks

Based on a community simplified-wiring discussion. The original post spans positive- and negative-ground conversions, so confirm polarity and regulator/rectifier pinout before connecting power. These recorded references do not establish that this circuit has been tested on your motorcycle. Match the installed components, polarity, terminal pinouts, wire sizes, and circuit protection to the relevant service documentation before applying power.

Verify your hardware pinouts, polarity, wire sizes, and component ratings before applying power.
