Match the round six-hole, four-wire connector and occupied wire positions to the harness. The switch replaces references 35100-303-007, 35100-292-003 and 35100-292-013. On a motorcycle with a changed loom, use the fitted connection and wiring information alongside these references.
The two featured combination units have different battery requirements. One is for standard lead-acid batteries; the other is lithium-ion only with a 14 V ±0.2 set point. Confirm the battery maker permits that set point and compare the existing stator wiring and mounting space.
No. The standard unit is for lead-acid batteries only. For the lithium-ion unit, confirm that its 14 V ±0.2 set point meets your specific battery maker’s requirements.
Check the six-hole housing, the four wires and their positions. A round connector with a different wiring arrangement still needs verification, especially after harness replacement or repair.
The lithium-ion unit measures 54 mm long, 57 mm wide and 35 mm high. Compare that envelope with the intended location and allow for the existing connections, especially if the mounting has been changed.
