9 pin connectors????

There are lots of these on eBay- my question is, what per circuit current rating is required? I’m thinking about led headlights, so the charging circuit is the only concern.

If you are replacing the stock headlights with led's, then the load will be less.  If you are adding lights then you might want to add up all the loads.

Run a wire from the regulator directly to the starter solenoid battery cable lug with a 30A inline fuse.

The early 520's did this and it really takes a lot of load off of the 9 pin.

Here is the early wire diagram for reference.
