Need wiring schematic

[susan90804]

I have a Sea Doo that doesn't have the identification tags on the hull. As close as I can tell, the 1990 electrical diagram matches my unit in all respects EXCEPT one item - the voltage regulator package (3 wire) is present in the battery cover above the recitifier, but the schematic shows no connections for this unit. I think the three wire are violet, white & brown??

Anybody have any idea what they are or where the go?????
